> they have the potential to make our life better
If you're a vegan as your nick suggests, i would suggest to reconsider this point. Capitalism was already bent on sending us towards a 6th mass species extinction (starting right under our noses), but so-called AI has changed the scale and speed of the curb drastically in only a few years. See for example this article for recent Google stats:
https://ketanjoshi.co/2026/07/01/googles-exponential-path-to-climate-w…
Recent AI datacenter projects such as Stratos (40000 acres) are on a scale of industrial destruction my mind fails to comprehend.
I'm not 100% vegan, but i'm 100% "AI-vegan", and i definitely would recommend you considering it.
PS: All i said was just about the environmental impact of LLMs. I suspect the human impact to be just as bad (cognitive impairment, accrued exploitation, etc).

As a counterpoint, I recommend this article: https://ketanjoshi.co/2024/08/12/texas-builds-clean-power-but-it-isnt-…
It looks into the numbers for the Texas renewable buildout, and there's a very important caveat: the amount of renewables you build is not the relevant metric. Emission reduction is. And Texas does not succeed there.

> that people they don't like at the old place are allowed to have opinions again.
Sorry, but I think that deliberately obfuscates the changes Musk has made at Twitter. See https://ketanjoshi.co/2024/04/19/you-are-the-fuel-that-energises-elon-… for one summary.
