Those medical "nanobots" that swim through the bloodstream are impressive but might instead be something on the micro scale, different from Drexler's vision of assemblers that can manipulate atoms and molecules

What the biggest hurdles and challenges preventing Drexler's nanomachines from happening?

If it's not possible, how close to it do you think we could get?

Swarms of "nanomachines, son" which can pull apart and process the waste, down to the molecule, and fully recycle all of it

Convince me that Drexler's nanomachines aren't possible.

If it's not possible, what are the biggest technical obstacles preventing it?
Energy requirements? Brownian motion? Components being too small to send or receive signals?
