They have a fiduciary duty to shareholders. Bailing on AI because they can't do that and also be net-zero is a good way to get sued.

Don’t the shareholders benefit from having an earth worth investing in that isn’t falling apart from climate catastrophe in a few decades?

Never before have I heard of lighting a pile of cash on fire being a fiduciary duty. Post-GPT AI may eventually prove a highly profitable venture - right now the only people making money are the shovel sellers and most of the launched applications can't seem to attract users at a price point that's sustainable.

Sued for what?

AI is not making anyone money except Nvidia.

Actually, fiduciary duty is not actually a mandate to be a maximal psychopath nor a mandate to spend billions on high risk investments.

As in, fiduciary duty does not prevent companies from being net-zero nor does it mandate AI.
