But if you want to assert that this time is different, there needs to exist evidence.
Such evidence should not be speculation. Such evidence should be things like "These quality of life metrics are going down, for these groups of people right NOW".
If this time is actually different, it should be measurable and provable, through quality of life or economic metrics.
But I don't think thats true. I think that society IS ready to handle the supposed "mass unemployment from entire categories of jobs being eliminated", as proven by the fact that it IS doing so, right now, because quality of life metrics aren't decreasing.
For example, the current us unemployment rate is around 4.1% (source: http://lmgtfy.com/?q=current+us+unemployment+rate)
I think a 4.1% unemployment rate pretty much proves that society is NOT devolving into a mass unemployment where robots take everyone's jobs.
