The article skips the potential upsides of an AI future - like curing diseases, abundance, merge type immortality. I'm keen myself with nothing to do with the goals of the 0.001% really. I think the future generations will like the above and look back on now like we look back at medieval dentistary.
Those upsides are currently just a fantasy and ignore the very real current downsides. They also do not in any way rely on AI to become a reality.
I have nothing against AI as a technology but the notion of it "curing diseases" is so silly. The limiting factors are largely in fundamental biology research and then human clinical trials. There is no plausible way that LLMs will make those activities 10× faster or cheaper. Hard work still has to be done in the messy real world outside of computers.
