What we're talking about here is the immanent arrival of it being impossible for a very large number of people to get a career in something they enjoy (making images by hand).

It's fair to suppose (albeit based on a very small sample size, i.e., the last couple hundred, abnormal years of history) that all sorts of new jobs will arise as a result of these changes- but it seems to me unreasonable to suppose that these new jobs of the future will necessarily be more interesting or enjoyable than the ones they destroyed. I think it's easy to imagine a case in which the jobs are all much less pleasant (even supposing we all are wealthier, which also isn't necessarily going to be true)- imagine a future where the remaining jobs are either managerial/ownership based in nature or manual labor. To me at least, it's a bleak prospect.
