You say that as if it wasn't true for anything human programmers ever produced
Humans can fly planes, computers too can fly planes. I'm not going to give the same leeway to a 'computer' flying a plane that I would to a human. Because we understand that humans are just that, humans. The demands placed on a computer are so very different.
Computers are already driving cars autonomously, possibly better than the average human already, and quite plausibly will eventually be better than the best human driver.
