Self replicating nanotech is what I’m referring to, yes. Doesn’t have to be a bacteria-like grey goo sea of nanobots, though. I’d generally expect nanotech to look more like a bunch of nanofactories, computers, energy collectors, and nanomachines to do various other jobs, and some of the nanofactories have the job of producing other nanofactories so that the whole system replicates itself. There wouldn’t be the constraint that there is with bacteria where each cell is in competition with all the others.
