Because the french believe in Liberté, Égalité, Fraternité. The first one the USA can fully agree on. But the second one, equality, is a deal breaker.

In this instance he is marketing what the final product is meant to do

He's been doing that with full self driving for the last decade and the event showed it might be a decade more. It doesn't give much confidence.

Ah yes, the "when brute force isn't working you ain't using enough of it" approach to AI.

Especially after promising self driving for a decade and then giving this little demo. It doesn't give much confidence for the robot to her autonomous anytime soon.

Meanwhile nurses and other care professionals are leaving the field. They love what they do, up to a point.

Many employers have tried the "if you love what you do, you'll love it without any raises, benefits or help." And now there's a lot of additional administration and bureaucracy to get all those important metrics and KPI.

Less people are willing to do the training for the job and more are leaving. Same thing happens for teachers, child care, elderly care.

It would be fun for that guy to discover transaction fees and wait times for crypto when he actually tries to pay with it.

Sometimes it's just easier to block some communities to get rid of the politics

The numbers are kinda meh for this. You have for example the gogoro scooters with swappable batteries. Each battery has about 2 kWh, weighs 10 kg.

That hydrogen cartridge I assume is about the same size as the battery and contains 5 liter, roughly a gallon. Hydrogen at 300 bar is 0.75 kWh / liter, so 3.75 kWh. Then it goes through a fuel cell at 50% efficiency and you get 1.9 kWh usage power. Not better than the battery. And if you want to power a car with, say 60 kWh battery car, it means 32 hydrogen canisters to swap.

There is also liquid hydrogen that has 2.36 kWh per liter. With 5 liter you get 5.9 kWh usage power per canister, almost triple the battery, but don't park these indoors. 10 of these are needed for a 60 kWh car.

For those scooters, the battery solution already works good.

It's not such as impressive amount of power compared to existing installations. Say 75 kWh battery. 80% of that would be 60 kWh, charged over 9 minutes. That's a 400 kW charger. Meanwhile 300 kW are reasonable common and there are a few 500 kW chargers out there. A 500 kW charger would charge the car to 80% in 7 minutes.

Camera pans down to the lower levels. Dark illuminated streets are visible, illuminated by sparse sunlight that manages to find cracks in the starship like road above. Flickering mismatched neon signs offer work, with long lines of broken humans waiting to find any job not taken over by AI and Optimus robots.

If things are at least progressing somewhat he predicts next year. For Musk to say 2-3 years means the project has hit a brick wall and they're desperate.

Where I live, there is a bus driver shortage leading to cancelled buses and limited service. Cyber cab, van or bus that runs the route outside of peak hours to give 24/7 service and monitor routes would be a big help. And it's a fixed route so the system can be optimized for those.
