I'm sure that the people working on making tinier & tinier robots are motivated by doing great things, but I think they're missing an obvious win.

Make #TinyBots or #NanoBots that can recognize detritus, crumbs, dust, even human finger oils.

I want to pour a jar of nanobots on my desk, & a few minutes later, there is no dust anywhere on my desk, the phone, the keyboard, the pens, etc. Everything on my desk is unmoved, but the dirt is gone.
