Nanotechnology: Is It Safe?

The video explores the potential and challenges of nanotechnology, highlighting its applications in various fields like medicine and electronics through carbon nanotubes. It discusses the controversies surrounding self-replicating nanobots and the hypothetical 'grey goo' scenario. The safety of nanoparticles is a concern, as their small size may increase toxicity, and some carbon nanotubes may pose health risks similar to asbestos. The video emphasizes the need for regulations to manage these risks while harnessing the benefits of nanotechnology.
