Part of the meaning of the word "singularity" is that you can't plan past it. It would be a period of such wildly rapid change and sensitive dependence on small details that you can't reasonably foresee afterward. It's not just AI itself, but all the other tech that could spring out of it.

Individually, I'm not sure it should alter anyone's plans beyond the already prevalent possibility of tech threatening your job and trying to position your self to be resilient to losing your job or changing jobs. On a policy level, we should try to organize so that more people work less rather than some people working not at all and some still working full time. Technology obviating jobs ought to be a good thing and only poor social planning can make it otherwise.
