Weren't people saying the same sort of things when the "assembly line" was first invented? After all, the main purpose of the "assembly line" was to make the same amount of stuff with fa fewer workers than had been needed previously.
I'm not saying this will be next year or so, and I'm not sure the parent post was meant to be exact with respect to the timeline. But, yeah, it's the kind of global direction we're heading towards. The ultimate goal is to replace of work done by humans by work done by machines, simply because we're lazy. that and the fact that capitalism is about gaining the benefits of someone else's work because you own the business. If owning robot overlords can assure you all you ever need without working, it's obvious everybody will want these, but only the most fortunate will afford it, leaving the rest of us in misery.
Oddly, we seem to have managed to get past the introduction of the assembly line without the sort of problems you're predicting - humanity is still here, its population is still growing, and technology is still advancing.
Isn't population growing mainly due to latency? Many second order systems simply overshoot before stabilizing. The mentality we have is still stuck in the post WWII era, were growth was over 5% every year and you could make plenty of kids without worrying for the future. I won't count on humanity to be something else than a pure reacting system, which means it will always adjust too late, contrarily to a predicting system (which is what individuals can be).
