you are now at that stage in life that you are not a small baby anymore, but a beautiful happy young kid!
Learning (more absorbing like a sponge) the environment. You are quite an observer, sometimes you just stop and keep watching, figuring stuff out, and when that eureka moment arrives it’s just magic and pure joy.
Like most kids in the world of ours today, you have quite an exposure to technology with always connected phones and tablets. With this comes the dopamine rush hits associated with the instant gratification of searching, installing and playing a new game in less than one minute, playing Youtube videos on demand and so on…
So… and I have to tell you this, sometimes it’s a battle to keep you offline and away the omnipresent screens… the good news is that you enjoy a lot the outside. You love to ride your bicycle, and you ride it pretty good for your age. We explore the lovely neighborhood (and some times beyond), go to the playground, the gardens, the riverside, the supermarkets, well practically everywhere with our pedal space ships.
You like stargazing and can easily identify Mars and Jupiter (yes they are planets 🙂 ), and to learn about the solar system and the magnitude of our magical universe. You find meditation quite intriguing, you also are developing taste for non commercial music, like classic Indian music, and more ecstatic rhythms to jump and dance to.
Not everything has been perfect an joyful, but guess what? That is the way of life, there is no light without the dark, no day without night, no yin without yang.
Unfortunately you experienced episode of violence at school, it shouldn’t have happened much less at this young age, much less at school, but unfortunately it did. Beyond the normal parents / school meetings you receive a pair of boxing gloves and bag, and once in while we do some basic drills. You like it, but in reality I’m tricking you, it’s really not about training to throw punches, it’s about training self confidence and paradoxically the right mindset to avoid violence. But beware, I don’t want you to be the weak victim, but oh boy, I sure also don’t want you to be the aggressor bully.
Also the last year and half was clouded by the Covid-19 pandemic. So sorry, for the endless time at home, the playgrounds, and parks closed. The good news is that it seems the vaccines are working, life nowadays (besides the omnipresent mask) is 90% normal. The best news is nobody that we love was lost to Covid-19.
As Covid-19 is clearing up, another health storm arrived this summer to make life difficult for us. My long term “relationship” with glaucoma took a significant dip. I’m sorry for so little quality time this summer compared to the previous ones, but this problem hit really hard kid and it took quite a lot of medical care, effort and interventions (we must give a special big thank you in this process to Dr. Feranado Vaz @HFF) to be now in a situation of hope. The most important thing is that everything possible to manage and tackle this problem is being done.
With a bit of luck will not be an impediment to this beautiful walk of life.
This post is on drafts now for about 2 years, it’s a concise summary of my Tesla investment thesis. My mental carburetor chocked at AI and autonomous driving… and guess what? I still have a shallow understanding of machine learning, neural nets, PyTorch, TPUs and all the technical stuff to deep dive into the AI stuff. And bear with me this stuff is crucial in my mind rational as Tesla’s business model is like a Trojan horse to deploy autonomous driving.
BUT no way that I could overcome my technical limitations… SO this post could stay in Drafts indefinitely, OR just like a IRL conversation with friends (congrats for the ones that actually invested) just wrap it up, and put out the general ideas to all my friends that unfortunately don’t have the opportunity to meet IRL so often.
Disclaimer: this is just my stream of consciousness, do not to take it as financial advise. DO YOUR OWN research and thinking. This can be the ramblings of a insane mind.
Humans, are quite an unsuccessful species about self conservation. We have a (declared) stockpile of nukes to destroy the total earth landmass SEVERAL times. The most important leader today doesn’t “believe” in climate change, and most of the others humans happily let the poison of the atmosphere, the water and the land to continue despite all the warnings.
Imagine a visitor from another world looking at this madness, probably we would be cataloged as “Technological savvy but totally schizophrenic species”. One must ask what legacy are we leaving to the next generations?
Anyway let’s be optimistic, continue the exercise and indulge into random thoughts and speculations about the future. Look and behold when one day the measure of computer RAM will be not in gigabytes, but in terabytes.
There is a revolution about the way people and cargo move around, probably the Jetsons flying car is not coming around soon (or probably it is in the form of electric VTOLs), but billions and billions are being spent into electrification of vehicles.
And this an extremely good thing, because a big chunk of total world CO2 and pollution is generated by burning stuff inside ICE (internal combustion engines), and the BEV (battery electric vehicle) is so much more efficient that it’s operation is much cleaner. And as the power grid gets greener with more renewables in the mix, the overall gap just gets bigger and bigger.
There are two metrics about batteries that don’t lie, the energy density Wh/L and the cost USD/kWh, and the trend is simple for both, higher energy density and less cost every year. It’s nothing at all like Moore’s law, much slower, but even predicting a very conservative 5% increase in density and 5% decrease in price every year, around 2050 (perhaps much sooner considering the massive resources allocations) BEVs will have the equal energy density at a fraction of cost of ICE. Factoring in the difference in engine efficiency, supply chain, and environmental impact, probably much sooner than 2050 will be the end of the ICE age.
Perhaps in a far future there will be internal combustion engines in museums showing the exquisite materials and craftsmanship of a time that the world was powered by an ordered symphony of tiny explosions. I imagine like something like a starting up and revving up event with all the attendees in highly protective gear…
Sometimes i see this video just for the comic entertainment value:
It’s so funny, this was June 2010, each TSLA share was selling at 17USD (3.4USD split adjusted…). Guess the market had different view… why was Jim Cramer so wrong?
Because he couldn’t understand inside his primate brain that the real transportation revolution is not the transition from liquid fuel to electric. No, that is just tip of the iceberg, the real revolution that’s going to turn everything upside down, it’s autonomous driving.
Think of all business around moving people and cargo, think of all the payrolls for professional drivers, think of all social security for professional drivers, think of all the road fatalities, think ride sharing and no ownership, think of long distance truck hauling, think of your car leave you on the spot and then proceed to park itself, think about drinking a coffee and finishing that report on your boring morning stop and go commute, think about going home drunk with no problem at all, think about catching some sleep on that long journey, think about elderly or disabled people who want to continue to go places by themselves…. etc, etc, etc…. it’s going to be a beautiful new world.
How much does it worth to have a total autonomous car system that can drive better than the top human drivers? That can operate 24/7 and doesn’t get tired, sleepy, drunk, nervous, over optimistic or distracted? A lot, really a LOT.
The race for the jackpot is on, with billions and billions being invested now. And where there is strong competition there will be results, and here Moore’s law is king, so expect this future to be nearer than generally expected. The company in the pole position is Tesla, and if they can deliver first probably they will become one of the most valuable companies in the world, probably the most valuable company in the world as autonomous driving implies solving computer vision, and computer vision achieved unlocks much more than autonomous driving.
Pushing forward deep into the future. We can ask this question, when an autonomous vehicle will be say 10x, 20x, or 100x safer than an average human driving, will human driving in public roads should be even allowed? Guess not, so I bet a lunch in the best restaurant in town with everyone that accepts the bet, that in 100 years from now human driving in Sweden (or Norway) will only be allowed in closed circuits (lets us hope the Nurburgring is still up and running).

as we can see with these few examples the machines are learning, and are learning more complex tasks and are learning faster. As of now machines are already at super human level at many tasks.
Sure driving is a task that one must parse several complex inputs (vision, sound, proper acceleration) and compute with context real time outputs (turning, accelerating, braking), but there is nothing magical or physical impossible for a machine to perform, and perform well better than an human.
Assuming hardware will keep improving offering better performance at lower price each year, and computer science AI and machine learning will also keep improving over time, there will be a point in time that these factors will compound and intersect to unlock autonomous driving, and Tesla with silicon valley tech know-how, best engineers in the world, huge fleet collecting real world data for training the neural networks, own chip designed specifically for artificial intelligence, etc, etc… will be (in my mind) the one company to unlock it first.
According to Tesla 2021 2q safety report, they recorded one crash for every 4.41 million miles driven in which drivers were using Autopilot technology (Autosteer and active safety features). For drivers who were not using Autopilot technology (no Autosteer and active safety features), they recorded one crash for every 1.2 million miles driven. By comparison, NHTSA’s most recent data shows that in the United States there is an automobile crash every 484,000 miles.
Some of the typical questions i have been asked IRL about the thesis:
Won’t legacy auto crush Tesla by sheer volume?
Well if that was to happen, it should have happened many moons ago. Tesla is a big boy now, growing fast with probably the strongest balance sheet in the industry. Besides legacy auto strength is in metal casting and folding, it can’t even put up a decent infotainment system… much more develop an autonomous driving system.
Besides legacy auto is in a world of pain, declining sales, convert factories and human resources to electric powertrains, battery supply, huge debts…. they are giants on clay feet.
OK, but the actual stock value has already risen tremendously, didn’t I missed the boat?
It’s a fact, the stock price already skyrocketed. If you invested 1000 USD back in the IPO and hold it (Jim told you to sell… big shout out to Jim) you would have today around 200.000 USD…
You can make a case to justify the current valuation on current business alone, you can go trough profit margins, growth rates, CAGR, ROI and other financial indicators, you can value Elon Musk as the modern Edison, but for me the equation is simple, if you can envision a near future with autonomous driving with Tesla leading, the valuation is cheap. If you can’t envision this, probably the valuation is more on the pricey side.
I’m not a big fan of reasoning by analogy, but I must also point that for disruptive companies, companies that change the world, with strong leadership and mission, companies that enter a positive loop feedback system it doesn’t make much sense to cap an upper limit.
“In the short run, the market is a voting machine but in the long run, it is a weighing machine.” – Benjamin Graham
Welcome to Portugal, the western little old rectangle of Europe. Full of history, beautiful monuments and castles, good food (better wine), awesome beaches and much more. The good news is that the country itself is small, so the main cities and points of interest are near each other.
First in the tour, the capital Lisbon of course. I suggest to start with a walk, a walk 1000 years back in time, when the Arabs ruled the city. Explore the very old and very narrow and steep streets and stairs of Alfama the oldest neighborhood of town.
Take your time (and take many photos) to go all the way up to St. Jorge castle. On the way up or down, route yourself to Miradouro de Santa Luzia for breathtaking sights, and to Sé Catedral the oldest church in town, and just 50 meters ahead? Another church! St. Anthony church marks the birthplace of the famous matchmaker saint, and he is always there (well his spirit anyway) just to help with every love problem of yours.
Leaving the old town follow the natural city expansion to downtown, this is the part of the city that was rebuilt after the 1755 earthquake, with straight and square streets, open spaces with lots of light, and beautiful architecture.
To give you a power boost, start in Rossio square just like a local drinking a shot of cherry liqueur called ginginha in the very small, yet historic, open-fronted bar A Ginginha. Just in front there is a small monument with the star of David, a tribute (and reminder) to the hundreds of people killed by the inquisition bonfire in the Lisbon massacre.
Take Rua Augusta and enjoy the walk to Praça do Comércio square, one of the big beautiful squares of Europe framed by the Tagus river, the bridge, and the boats. Proceed with the river on your left to Cais do Sodré, a place full of bars and restaurants ready to satisfy your famine and thirst. You should check out Pensao Amor an old brothel converterted into a fancy bar that actually kept some charm.
Beware, Cais do Sodré is just one of those places lost to gentrification. Pink street has too many tourists, few locals. Lots of bars and restaurants with little to no soul. High prices alert!
Time to move up to Chiado the posh neighborhood and the adjacent Bairro Alto the classic nightlife quarter. In Chiado please do take a coffee at A Brasileira with Fernando Pessoa (a famous dead poet) or if it’s the end of the day a drink (and a haircut) at O Purista. Do some shopping, the finest shops in town are in Chiado (and also in Avenida da Liberdade), checkout Livraria Bertrand, the oldest book store in the world, selling knowledge stamped on dead trees since 1732!
Bairro Alto comes alive at night, packed with restaurants, bars and people happily roaming the streets. Close to S. Pedro de Alcantara viewpoint I strongly suggest a drink in Pavilhão Chinês, one of the most beautiful bars in Lisbon. Also in Bairro Alto you will find Tasca do Chico, one of the last strongholds of bummer fado music. You can come in sit down have a glass of red wine and enjoy. Also a very good option to seat down, have a drink, and listen to fado, is Mesa de Frades in Alfama.
Fado nowadays is mostly served in an expensive tourist package sold by the hotels that includes the transportation, fado museum, fine dinner (this and that), and fado presentations. I’m pretty sure that you will eat good and enjoy your time if you choose this option but the bummer fado is way cheaper and perhaps more authentic.
Back to daytime you should visit Belém, still Lisbon just a bit off the city center, this is the district that best symbolizes the portuguese age of exploration and discovery. Easily reachable by train from Cais do Sodré heading to Cascais (just a couple of stops between), there you will find the iconic Belém Tower, a fortification dating back to the fifteen hundreds, the Jerónimos monastery dating back to the sixteen hundreds, also Padrão dos Descobrimentos a beautiful monument dating back to 1960 dedicated to prince Henry the navigator and the portuguese that discovered the roads of the sea.
And of course, for me the main highlight of Belém, and the reason of all the work and hassle of sending boats filled with men across the globe, the Pastéis de Belém factory. So remember and praise all the history behind the moment you dust with cinnamon the delicious egg tart pastry.
And you are done with Lisbon city highlights. But please reserve one more day in town and do the day trip do Sintra, Cabo da Roca and Cascais. You can get to Sintra from Rossio train station (about 1h), from Sintra do Cabo da Roca by bus (about 30m), Cabo da Roca to Cascais by bus (about 20m) and Cascais train back to Cais do Sodré station (about 1h). And I really suggest to do Sintra in daytime, Cabo da Roca end of the day, Cascais at sunset/night.
Sintra is all about palaces, beautiful nature, castles, legends, knights Templar, moors, elves, fairies, and BAD WEATHER, so try to choose a perfect sunshiny day.
Right in the center of the village you will find the Town Palace (the one with two distinctive chimneys) even though is the most visited would strongly advise a skip to this one… because climbing up up up the hill (there are buses available) you will find the much more beautiful Pena Palace, just like a fairy tale construction, sitting proudly on the top of he ridge with breathtaking views and mind blowing gardens. Also would strongly advise a visit to Quinta da Regaleira, and also to the “small” but exquisitely beautiful red domed Monserrate Palace with exotic gardens and strong Moorish influences.
If you have time go to Cabo da Roca, the western point of continental Europe for some cool photos. If you love motorbikes, you definitely should go because there are always lots of cool bikes there so it’s a plus. If you spent to much time in Sintra then proceed straight to Cascais. Once a small fisherman’s village, now the Portuguese riviera, the perfect place to eat, drink and have some fun before returning back to Lisbon (or maybe to stay a couple of days to enjoy the easy going life, party at night, and the sun, surf, and sandy beaches at day) . For more detailed information please refer to this post about the area.
One more thing, when you move around in Lisbon please take a bit of time and do the classic 28 tram line thru the 7 hills. Usually is very crowded, so try to go really soon or late at dinner time. Buy the tickets before in the subway (much cheaper), and pay attention to your wallet (some pickpockets work daily in the trams).
If you are travelling with kids, and / or never went to a massive aquarium, please consider going to Lisbon Oceanarium. Located in the posh neighborhood of Parque das Nações it’s the flagship from 1998 World Fair, is the largest indoor aquarium in Europe, and truth to be told, if you have some kind of affinity with the ocean, it’s just an awesome sight to contemplate the main tank.
Decisions time… if you fell in love with Lisbon, just hang around for the rest of your stay, enjoy time slowing down, the city light and the city night, drink lots of coffee and wine, make friends, explore the less touristic spots. If it’s Summer, and it’s hot, and you are dreaming of a city break, go ahead and take the 3 hour bus to Algarve, beautiful sandy beaches with warm water wait you there, after all the city bustle it’s a well deserved rest.
But if you really want to know the true soul of Portugal you must head North, not just because of monuments and landmarks but mainly because of people, honest, straight forward, with strong values and traditions, are probably the best hosts in the world. Also the food up North… delicious.
Heading North, the best way to do it is with a rented car but you can also do it by bus. Start early in the day, first stop Óbidos a well preserved fortified medieval village with a castle. Several times during the year the village celebrates the middle Ages with parades, markets, and more, so definitively check it out. Next stop, Nazaré – Praia do Norte, home of giant waves and the spot with the world record of biggest wave ever surfed. When conditions are good and surfers are in the water the view from the lighthouse is amazing.
Next stop Batalha monastery, an heritage monument celebrating the 1385 battle of Aljubarrota victory over the Spanish. I invite you to continue in the religious trail and visit the nearby Sanctuary of Fátima, place of many miracles, apparitions, celebrations, and many pilgrims.
Eventually you will arrive at Oporto the second city of Portugal and the capital of the north. It’s not my hometown like Lisbon, so do some research about it. I can strongly suggest is a visit to Vila Nova de Gaia port wine cellars. There are many of them, and it’s a really fun afternoon to visit some of them and tasting the nectar of the gods. For the definitive port wine experience there are several tours up the river Douro into the vineyards with visits, fine dining, and overnight stays in the producers farms.
That’s it folks, my personal suggestions for a week in Portugal.
One more thing, the food… everywhere you can eat really good with reasonable to exceptionally good prices. So, don’t waste your time, money, and body in MacDs or BKs that taste the same shit everywhere.
Some places that you should try: Verde Minho – Honest old fashion portuguese food. In the center of Lisbon and great prices. Cervejaria Trindade – in Chiado, old monastery (different and beautiful architecture for a restaurant). Good steaks and “pregos”. Not cheap nor very expensive. Novo Edmundo – Grilled meat and typical food. Outside the city center, good price quality quantity relation. Tasca da Esquina – Portuguese fine dining. Gourmet experience. Expensive (for Portuguese standards). Put yourself in the hands of the chef. Cervejaria Ramiro – if you are into seafood this is the place to go in Lisbon. Lots of tourists and queuing since the late Anthony Bourdain filmed No Reservations here . A bit expensive to very expensive (varies a lot with the seafood you order). Viveiros do Atlântico – 30 minutes north of Lisbon, in the picturesque surf village of Ericeira the seafood is also great and not so expensive as Ramiro. If it’s full or closed, in 1 kilometer radius around it, there are many other good seafood places. Nova Casa dos Leitões – Perhaps the best roasted suckling pig in your life… up north in Anadia.
Thank you for being alive, thank you for understanding, science, and medicine. Thank you for my beautiful child, thank you for unconditional love, thank you for all the park mornings and afternoon beach sunsets, thank you for all the laughs, hugs, walks, slides and swings. Thank you for all the learning.
Thank you for all the people in my life that I love. Thank you for music being omnipresent. Thank you for my business, economic grow, and abundance. Thank you for the good food and better wine of this land. Thank you for the mesmerizing nature of this world . Thank you for the safe motorcycle rides. Thank you living my dreams.
700 days have elapsed since you were born, so now you are a very happy (and big!) 20 month baby. And boy… you warped the space time continuum to a incredibly fast pace.
It’s such a big joy to see you move around and discover the world. And you do move, explore and interact a lot. One must always keep a close eye on you, because you like to touch everything and climb stuff… the cherry on top of the cake, is that at night time usually you are so tired that you fall asleep in minutes.
You are starting to talk, you know the normal stuff “mamã, papá, sim, não, água, papa”, but also some really cute things: usually when something is done you say loud and clear “Já tá”, another personal favorite is when you pursuit the house cat with a great smile on the face and say “Piiii, Piiii, Piiiiiiiii” (it’s a hard life for the cat…).
You still smile a lot (you practically born smiling…), and with your smile you make many people smile also, some that I actually never saw smile before you. Please don’t ever loose that inner happiness, it’s awesome.
In these months I have learned many things about life with you kid, children are really the best thing in the world because they change adults to a better version, more calm, more optimistic, with more inner strength.
You know, my biggest wish is just to be remembered as a good father.
