There is absolutely zero will in the United States to invest money in unprofitable exploration or scientific research. There used to be such will generations ago, but today's wannabee-autocrats couldn't care less. Look at how they gleefully cut scientific research funding, undermine academic sovereignty, and strip-mine the public sector performing that work in favor of private enterprises. When the shit hits the fan and we're all broke because the corpos laid everybody off for Devin, Claude, and Clippy, there won't be much left besides surrogacy and plasma donation.
Patronage programs for people with advanced degrees is a woefully inadequate solution to the current economic pressures. Large segments of the first-world working and middle classes hollowed out by globalization had already turned against it before AI even came on to the scene. People are generally hostile to patronage directed towards people above them on the ladder.
Look into how much of that research money actually goes to research and how much goes to administration. And since that administration has a reputation for being to the left of Mao, perhaps then you can understand the unwillingness to put money there. It isn't that people don't want to invest in research, they have lost faith that the money allocated will actually get to the researchers.
That is perhaps the current administration, may be we do need a visionary in government again
