In terms of what the world looks like.. Probably largely similar.
As I said to someone earlier - AI is a tool, like a computer. It exists to automate away some tasks and if use properly, create leverage for the user.
If you can further automate some of that leverage (by having the machine execute some economic tasks) you can increase the leverage, and ideally do more with less.
It's the been the same store with automation, tools and technology since the beginning of time
