This is not even close to true, though it's true that many of the people at the big AI labs estimate non-trivial odds of human extinction downstream of AI progress. Some of those people are working on "safety", but some are indeed working on capabilities, and have all sorts of clever reasons for why the thing they're doing is net-good (like putting worse odds on human survival if a less-careful competitor gets there first). But ultimately, most people who think we stand a decent chance of dying because of this are not working at AI labs.
