Exactly, I am totally fine with us spending some tax dollars to try out these absolutely insane ideas. But this isn't a matter of "let's spend more" because the pool of people that can see an absolutely insane idea, and ones that can actually work on them, are the vanishingly small number of nearly eccentrics. So there is an upper limit on how much money can be spent if you're at the absolute tip of the iceberg.

> because the pool of people that can see an absolutely insane idea, and ones that can actually work on them, are the vanishingly small number of nearly eccentrics. I go back and forth with this. The further along the path I go, the more I weight good faith and sincere will to make a thing over ability-at-start. (drive + moxy + curious + perceptive - ego) is a better function to optimize for than buzzword count on a…

But take something like quantum computing… even “conventional” computing has gotten to a point where there are a vanishingly small number of companies that can do anything with it.

ASML is the only company that can do EUV lithography, right? NVDA and AMD are the only game in town for high performance graphics cards.

So how many people are going to be able to move quantum computing forward? Theory, hardware, investment, etc.

Same with, say, supersonic and hypersonic flight. Only 2-3 governments have been able to build them.

It’s a combination of mostly money but also the talent. Only google has got as far as they did with autonomous driving.

Although a counterpoint to my above point would be autonomous driving. Seeing the number of teams that succeeded the first time in the DARPA grand challenge vs years later, shows that a whole ecosystem was able to build up with the right encouragement.

So maybe I’m also going back and forth on this one like you. :-)

You're right, there seems to be iron rich deep sea currents in some places that could be good opportunities for upwelling, especially if you had a carbon neutral way to do it. There is also emerging technology for nitrogen fixing that could work - Electrocatalytic Nitrogen Reduction. All this being said, if the goal is carbon sequestration building a viable business is going to be next to impossible. The easiest way…

Carbon sequestration is merely a side effect, the main goal is to have a wavebreaker and a park and a place to grow fruits, for a floating city. To bring nutrient rich water up and to generate energy in the process temperature difference between surface and deep water can be used [1]. So if this kind of tree is created, living on open sea can become cheaper and more pleasant than even living on a beach. [1] https://e…

Ok, I was misunderstanding.

Ocean thermal energy conversion - I hadn't heard of this, this is awesome.
