Yeah. That 70s one was very crude mechanically, and given 50 years I imagine the flight technology has been much improved. The electronics, for sure, and power technology now packs a lot of energy in low volume. So these things can go farther and be more complicated.

Also, the computer nano tech is now so small it can be put in vaccines, which is why we see vaxed people with Bluetooth IDs in their body now.

My old physics professor Feynman in the 60s funded a contest for primitive micromechanics. The winner was a guy who built a motor the size of a pinhead. They displayed it under a microscope in a case in the physics building hallway. When you pushed a button it ran. The technology evolved into different ways and now, we can make nanosize gyroscopes out of silicon and they are in every phone. Companies like SciTime sell such parts cheap. The military, with money to burn, is doing things straight out of science fiction now.
