we are probably not going to keep pumping CO2 out at the rate of the worst case scenario of business because believe it or not companies are aware there is little profit to be made from dead consumers.
The realistic scenarios are still pretty bad but less so.
Just assuming LLMs will scale to the point of being more useful as all these companies are banking on is not unfounded but it's also just an educated guess because of their own optimistic prediction they will be able to bring about a new fascist world they are in charge of before they run out of money. It's very likely we are all screwed but it's also very likely LLMs will not scale up fast enough so they can replace the majority of human labor.
