Ask a Scientist – Nano expert: Quinn A. Spadola

The video addresses concerns about nanobots replicating and taking over the world, comparing them to viruses, which are nature's nanobots. It explains that both are limited by resources and competition, preventing them from dominating. The conclusion is that if viruses haven't taken over, nanobots likely won't either.

In what way would nanobots compete with each other?

Why does the speaker believe that nanobots won't take over the world?
