I think the HN crowd forgets that what really runs the world are min wage workers running around and doing real world things, not code monkeys and glorified type writers filling excel sheets. So yes, replacing the bullshit jobs we invented to keep people busy will be relatively easy, that's if you don't account for the fact you'll now have to create bullshit+ jobs to keep them busy
And even then we're far away, sure it can shit out code for a todo webapp and create semi realistic images of a monkey eating a burrito but that's about it. More than a year ago someone betted against me here that chatgpt would revolutionise the world in the next year, nothing happened really, geeks are excited, execs are buying the hype, tons of money is transferred, yet there was no 4th industrial revolution.
What happened though is that the web is flooded with absolutely useless content, amazon is full of ai generated books, students rely more and more on chatgpt to generate homeworks, thesis, "find" solutions, &c. it might very well end up being a net negative for the average joe in the long run
