All well replacing mundane jobs with robots, but what will those displaced workers do. Also come 2030, the population will of increased, which will be mostly in the demographics who lost their jobs to robots in the first place.

But then the whole cost effective argument is from a company perspective, what it costs them on the balance sheets.

The fallout and full cost of loosing workers is very much ringfenced for companies, but the social impacts can be far far deeper and far more costly to a community than any saving made on a balance sheet.

So I get the whole workers rights perspective, equally, I'm mindful that some jobs really are not fit for humans, just because they can do them, don't mean we can't technology them away. But a balance is needed, so if they had a robot tax as many have raised and mooted in the past, then perhaps that could be used to find education, free recreational activities. Otherwise we will just fuel an endless supply of humans in production line style that feel useless in society and become statisticaly abandoned or worse.

Certainly won't need 20M robot maintenance jobs, let alone the skill set from picking fruit and moving onto robot maintenance for many will be a transition out of their reach.

So all yay for robots replacing menial jobs, but let's make sure such displaced menial workers are afforded some education and opportunity into better jobs. Otherwise it will not end well socially.
