Thinking specifically of scuba diving. It requires a ton of equipment and training and can still be dangerous. In movies there’s always some kind of little gadget that allows people to breathe underwater without all that equipment. Why can’t we build a simple mouth piece with an oxygen canister attached that we could carry around and breathe into when we need?

That is exactly what a scuba setup is…
You could use a smaller tank but then you get less time underwater. You could get rid of the second regulator but then you are compromising safety. You could get rid of the buoyancy control device but then you can’t control your buoyancy.
Scuba needs training and could be dangerous because you are spending time underwater, not because of the specific equipment.
