Which leads to things not getting patched, more bugs, and more computers getting hacked. A great system...
I'll also add that if it was a big enough bug that it'd end up on the news and that's how people got informed. Otherwise, like you suggest, good luck. But it was possible.
It is baffling to me that we are having this conversation on Hacker News of all places. Aren't we a community of programmers? How in the world does any programmer think for a hot second that code is bug free? Last I checked formally verifying your code was 1) very rare and 2) still impractical if not impossible for anything of sufficient complexity. Unless we're formally verifying our code, I absolutely guarantee it has bugs. I know we have big egos, but egos so big that we think we're omniscient?
