That is a stupid statement
You dont know squat sqigg
How is that statement stupid? Because it's redundant?
All it does is point out the obvious, which you chose to overlook. Everything is not possible. For instance, can you be a cat? No, you're a human--you can't be a cat. Therefore your statement that everything is possible is wrong and stupid.
When it comes to tiny MAVs, you're right--I don't know a huge amount about that stuff. I do have a good understanding that we don't have the right materials yet to do that kind of thing. There are some engineering barriers to producing something remote controlled and mosquito sized. There's plenty of reading you can do to convince yourself of this, but yes I can admit it's possible there's some shit we don't all know about yet.
When it comes to nanobots, not a chance. This is in my wheelhouse. We're super far away from having these. If we were even CLOSE there would be some carry over into "known" science from that. We're quite far away from having this type of technology--we're still learning about nanoparticles and how we can use these, functional nanomachines with directed uses are out of our grasp right now. We're still developing the "machinery" that will go into these.
