I can see this happening. Technology is evolving at such a fast rate, that we won't be able to keep up. We're already losing some jobs in favor of machines and it seems to improve our experience as customers while other persons get affected at the same time because their spot gets taken and as this spreads, the likelihood of finding a job shortens. Thing is, I don't think jobs will entirely disappear, or rather, making an income with any kind of activity. If anything, look at ourselves right now, we're on a site that's basically paying us for doing this. What I can see happening, is cash completely disappearing, currency being this digital thing, and if anything, we'll be like those people on the movie Wall-E, where machines do everything for them, literally anything, they don't even have to walk themselves, and while all the jobs and manual labor could be handled by machines and AI, we could make an income on other activities that don't have to necessarily be machine exclusives. But then you think, how long would that last? Or, would our income come from testing new AI and help perfect it by social interaction on the internet and stuff like that? As long as trial and error methods are still useful, humanity can still have a purpose, that's gonna be really hard to get rid of, trial and error I mean.

Probably I'm just being a bit naive, but it was an interesting read, and a real and valid concern as any.
