Tellingly, our president only instigated a review after the news was all over the major national outlets, not when student journalists first broke the story. Small surprise, as the two have been speaking on AI with one voice and helping make travesty of education jointly

The college at which I teach, Dartmouth, rose from 200-something to #6 for free speech in FIRE’s rankings. I believe this is misleading. This feels to me & many colleagues like the most restrictive atmosphere we can recall. & many students tell me confidentially they censor themselves about AI.

We already do this and companies who want them are happy to pay for PhD student interns. Why do precious and limited NSF funds need to be deployed for this? Most PhD student pursue industry jobs anyways - that has always been true. Use NSF funds to support basic science that industry wont support!

The U.S. Secretary of Defense just stated that—so far—the war with Iran has cost $37.5 billion dollars. That's since February. That same amount is how much the United States spent on planetary science from FY2013 through FY2026 inclusive. Thirteen years of planetary science or five months of war.
The Curiosity rover on Mars. At about $2.6 billion, it buys you about ten days of Iran war.
