If there is true AGI, I don't see the reason why 99% of the population would have a reason to stay employed If there is AGI AND enough computing power, it will either make social mobility disappear because everyone would be up the socio-economic ladder, or it's an apocalypse, there is no in between. During the time there isn't enough computing power for every jobs, but running it costs less than a salary, then I guess there would be high unemployment rates for a few years.
