"alignment researchers tend to be in house philosophers on staff" - this is definitely not true. Go to any alignment lab like Redwood research and check what their scientists studied on LinkedIn, 75%+ of the time it's math or CS.

I attend a top 10 Canadian university and personally know at least 4 tenured CS professors out of the 7 I've asked who are deeply concerned about catastrophic AI risks from loss of control.

Of course not 100% of the field agrees, but a survey of nearly 3,000 AI scientists who have published in top AI venues found that "depending on how we asked, between 38% and 51% of respondents gave at least a 10% chance to advanced AI leading to outcomes as bad as human extinction", let alone loss-of-control risks less severe than extinction.

Not to mention Geoffrey Hinton, a Nobel prize winner, Bengio, the world's most cited scientist, and scientists like Stephen Hawking and Alan Turing have all voiced series concerns about loss of control of artificial intelligence.
