If programmers built houses, every 20th time you tried to walk up the stairs, they would fall down for no apparent reason.

Seriously, I know if hackers built houses they'd have a lot more "features," but given how often my IDE crashes, I'd rather an architect design my home...

Then, they'd reset the stairs exactly like they were before and tell you to just keep using them for a while, and let them know if it happens again.
