It may work that way. But, consider this. In the 1800s, people worried that photography would stop art. Instead, we got Impressionists, then Expressionists, and on through decades of entirely new art.

Human perception is a creative process that builds our model of reality. How can creation stop?

The best thing is to read to them. It makes them love books and associate reading with together time.

I don't know why. There's a deep imperative to create and AI researchers are among the most creative people on the planet.

I lead a team building AI to support human decisions. To make this really work, we need fully transparent decision models. Neural net lack of transparency makes them dangerous.

Trump should think about this some more. Canada has roughly 1/10 the population of the USA. Its 10 Provinces would create states 51 to 60. That means 20 left-leaning Senators, and 40 or so new Members of Congress. It would be a woke reverse takeover.

Summary of green hydrogen for consumer transportation answers:
Current production & distribution economics are not viable.
Technology is very early stage.
Fuel cell costs 10x batteries & will stay that way as both technologies mature.
Green hydrogen has better much uses.

5) Electricity is readily available through infrastructure paid for by other economic activities. Many who afford cars add charging where they live at a small incremental cost. Green hydrogen is uneconomical, subsidized & distributed to only a handful of locations worldwide.

4) This itemizes economic, technical, & political barriers to green hydrogen based industrial technology, based on stakeholder input. The technology is immature, incentives are misaligned & market uneconomical.

3) Battery electric vehicles have now reached price parity with most segments of the internal combustion vehicle market. Economies of scale & competition are driving costs lower. Fuel cells can't compete now, and even the most optimistic estimates don't show them catching up.

2) It looks like consumer costs for vehicles are not included. Fuel cells cost 10x to 15x what equivalent batteries do. Assuming cost drops 90% over the next 15 years (like it did for batteries), fuel cells will still cost $10k per vehicle. (equals $200 billion - best case).

@h2emanuel.bsky.social‬
1) It looks like this estimate assumes that energy for H2 generation is essentially free because it comes from excess renewables during peak generation. Best estimates for fuel cell efficiency in 15 years is 60% vs. 90% for batteries i.e.: fuel cells require 50% more energy.

He'll be selling $25 official Trump felt markers to MAGA so they can update all the maps.

I've consulted on infrastructure planning for utility companies, & regulators and WECC. The key issue with predictive modeling is properly capturing the externalities and understanding how economics interact with technology development and adoption. It'll take me a little while to dig into this.

Thanks for this link. I'll check it out.

Current hydrogen vehicles are driven by fossil fuels because green hydrogen is currently too expensive.

95% of hydrogen is grey - produced in a way that released CO2.

4% if blue - where the CO2 is captured and sequestered.

1% is green from electrolysis. This costs 4x Grey and 2x blue to produce.

I' against tailpipe emissions - I just don't see hydrogen as the best solution. Battery electric vehicles are cheaper, more efficient, and utilize existing infrastructure.

Green hydrogen may make sense in some fleet operations with centralized refueling (e.g.: LA Port) but not for private vehicles.

EVs are scaling well. Norway led the way. China is on an S-curve adoption.

FCEVs do not scale well. Capacity for green H2 production, storage, delivery & retail distribution would have to scale 1000x (100,000%) to replace the current vehicle fleet.
