Perhaps the quantity of labour utilizing each new technology through time is a (n-shaped) parabola that intersects with the technology it replaced.
The fear that technological advances will cause mass unemployment and destroy labour markets has been common throughout history. Yet here we are at full employment. Maybe this time is different?
It is different this time. In the past automation effected some domains more and some domains not at all. People moved to those other domains. AI can run all the domains humans do and more that they can't.
