Exactly.

The moral of every Hollywood Racism Movie^TM ends up boiling down to “We could eliminate racism if only every racist met a person of [RACE] that they actually liked.”

Practically everything people say about imaginary numbers you could also say about negative numbers.

Also… wrong about what?

I guess the main thing is that it’s not just one person saying “I looked at the code and didn’t find any malware” - depending on the size of the project it could be millions of people saying that. Also, changes to programs generally have to be approved by the maintainer, so it can be pretty difficult to slip malicious changes in unnoticed.

The arrangement isn’t perfect, but keep in mind that closed-source software also requires trust on the part of the users - It’s just that in that case nobody can vet the code.
