🧪⚛️ Most researchers don't choose a country but a receptive environment for work, and nimbly move across continents to do so.
The proposed cuts in federal funding would create a hostile environment that could repel the next generation of scientists from the US. This'd be a major loss for the nation.

Oof. Another instance of mistaking quantum theory as a theory of consciousness or a theory of mind. People, if they could exist, would have free will even in a completely classic, deterministic world.
Whether or not we have partial free will could soon be resolved by experiments in quantum physics, with potential consequences for everything from religion to quantum computers
Do we have free will? Quantum experiments may soon reveal the answer

I keep seeing the puzzled question: why all the cuts to science funding? Don't they know it harms our economy?
The answer is simple—it's what all culture warriors & ideologues do: a cultural revolution.
Where they can, they close the universities. Where they can't, they cut their funding.
