do you really believe this? wow, the Kool-Aid effect is real. So many problems with this argument.
> If people spend less time building a unit of output, then you have more output.
there isn't infinite demand for the output. unless they're in an industry with infinity growing demand (which would be ...?), companies are not going to retain their staff and 5x their output, they are going to cut their staff by 80% and 5x their profits. we're already seeing this (not 80% but things are just getting started).
> People aren’t going to stop wanting stuff.
wanting stuff and being able to afford stuff are two very different things. if people don't have jobs, they can't buy that much stuff. This is why we will end up with a few very large and profitable providers.
> Right now, the world can’t come close to making all the stuff people want.
Completely false.
> As long as there’s a desire for further consumption, there will be work for people to do.
No. As long as there is continued consumption, there will be a demand for output of companies most of which will (if the promise of AI holds true) not be fulfilled by humans.
