Look at horses: thousands of years of utility, now essentially decorations and luxury items. Their population virtually gone in 100 years.
No one has explained to me why that won't happen to humans except "it hasn't happened yet" and "humans aren't horses (duh!)", neither of which really addresses the issue.
So per capita, there's 1/6th the horses of 100 years ago.
once serious automation takes holds not all meat popsicles will be of worth equally.. even today humans in US are worth a lot more than say iraq. this will only get worse as haves can have entire production capacity without giving 'handouts' to the poor burger flipper just made obsolete by robot. IMO the time for UBI or such schemes is before serious automation hits so we can scale it up NOT after as it'll be too late then. It rarely happens that people give up power & influence voluntarily.
