> we have no reason to believe their statements about risks are insincere

Why? Because they said it a few times? Then if they know the risk, why do they still making it? Comes out the "some one will do it eventually, better be us 'good' people to do it first" talking point?

See? It is a marketing strategy after all. These all talks, it's all to fit themselves into the "'good' people" narrative. It's a centuries old strategy to shield it's user from responsibilities while luring the support from the stupid.

However, the most harmful damage, which is mass layoffs, is already partially done. This could really kill, a massive genocide even, by making people jobless and potentially incomeless. And it is shown that these tech CEOs, they don't care any bit of that beyond the point "I've already told you so".
