Sam pontificated about fusion power, even here on HN. Beyond investing in Helion, what did he do? Worldcoin. Tempting impoverished people to give up biometric data in exchange for some crypto. And serving as the face of mass-market consumer AI. Clearly that's more cool, and more attractive to VCs.
Meanwhile, what have fusion scientists and engineers done? They kept on going, including by developing ML systems for pure technological effect. Day after day. They got to a breakthrough just this year. Scientists and engineers in national labs, universities, and elsewhere show what a real commitment to technological progress looks like.
And everywhere. You've only named public institutions for some reason, but a lot of progress happens in the private sector. And that demonstrates real commitment, because they're not spending other people's money.
