I would bet that more people know what a transistor is than what a brain cell is.
No chance. Everyone knows what a brain cell is, to some extent. Even people who have too few to rub together don't really feel like they know what a transistor is after reading the Wikipedia page for them, twice...
I used to know what a transistor was. And then we shrunk them to the point where they are no longer the same thing and yet they are still a thing, so I don't know what they are anymore.
