There isn't a feasible plan, we're at the "sounding the alarm part." Unfortunately, we're still there because most people don't even acknowledge the possible danger. We can't get to a feasible plan until people actually agree there's a danger. Climate change is 1 step past, that there is a danger, but not a feasible plan.
However, your solution is first day naivety for the problems machine intelligence poses to us. It's akin to saying everybody should have powerful mini-nukes so that they can defend themselves.
a) what is currently being touted as AI is neither artificial, nor is it intelligent. This is a bunch of hucksters saying "we made a scary demon with powers and now we're scared it's going to kill us all!" but in fact it's just a plagiarism machine, a stochastic parrot. Yes, it will get more useful as time goes on, but the main blockade is always going to be access to compute capacity, and the only viable solution to that is a socialist approach to all data processing infrastructure.
b) even if we stipulate that there is a scary daemon that could consume us all (and meanwhile teach me linear algebra and C++), and we transform that into pocket nukes as a more terrifying metaphor cause why not, your solution seems to be to pretend that your mini-nukes cannot be assembled from parts at hand by anyone who knows a bit of Python.
