Claiming your product increases the risk of extinction doesn't sound like something someone would do if it were just for fiduciary duty.
If their activities materially increase the probability of human extinction and this poses a risk of potential loss to shareholders then they must disclose it.
"Our product is so amazingly powerful that it just might result in the extinction of the human race."
A lot of people will only hear half of that sentence. Semantically speaking.
Ok.
So… follow out your own line of thinking. Altman and Dario and whoever is at Google are all saying the same thing, and are all required to make moves better for business…
Scaring tue gov into regulation - is good for business.
Another mark in the “they clearly want regulatory capture” column.
Consider the amount of debt they have piled up. If you don't believe your company can lice up to said debt or the current valuation, and if you do believe fear can lead to government capture that would protect your company from said liabilities, fiduciary liability would incentivize you to push the extinction risk narrative.
