I suppose as long as either humans are always able to use new tools to create new jobs, or the wealth gets shared in a fully automated society, it won't be ominous. There are other scenarios.

I think we might make new jobs, but maybe not enough. I'll be pleasantly surprised if we get good at sharing wealth over the next few years. Maybe something like UBI will become so obviously necessary that it becomes politically feasible, I don't know. I suspect we'll probably limp along for awhile in mediocrity. Then we'll die. Same as it ever was. The important thing is to have fun with it.
