Could this escalate to the point that Anthropic exits the US and sets up shop elsewhere? Or would the company cease to exist before it got to that point?
Best scenario it will get TikTok-ed, otherwise it will become the real national security risk
Had the exit happen, well, as US has a monopoly of compute on this planet for next 2-3 years at least, the company, even though they would take the researchers with them, will certainly cease to exist as it exists now.
Hegseth's statement already leans towards accusations of treason and duplicity, I would say people trying to export the company would face significant risk of arrest or worse.
