This article is a work of fiction, interesting to read as entertainment, but definitely not a rigorous model.

The premise that just because a lot of investment goes into AI infrastructure means that it has to displace the entire workforce globally is wrong to begin with.

It even admits at the end that the scenario presented is unlikely: "I don’t want to dwell on whether AI can do what these companies claim. It may well be able to, though the current evidence suggests the gap between pitch and product is vast, and serious economists think the productivity gains are a fraction of what the industry projects."

It begs the question, what's the point in being alarmist and anxious about something that even you claim it's unlikely to happen?
