ALL CLEAR!
Obviously, the apocalypse didn't come to pass.
Nothing really came of the y2k bug.
How did we dodge it?
The truth is that computer scientists had been tackling the issue of y2k for years before it entered the public zeitgeist.
People who worked regularly with computers had started to notice something was the matter as early as the 80s. Entities like insurance companies and the Social Security Adminstration who made use of computers to prepare things for future dates ran into issues when attempting to deal with dates after 2000. Soon enough, these entites started spending billons of dollars collectively to pour through all their code with a fine toothed comb. It wasn't glamourous work, it was long and tedius. And it was done by thousands, maybe millions, of different programmers and computer engineers. But, by the time 1999 rolled around and the general populus really began to panic, professionals had already been taking the issue very seriously.
It was hard for the public to understand this, though. Computer science is a very 'behind the scenes' industry. That, combined with the fact that there was no one programmer or even organization responsible for fixing the y2k bug who could be pointed to, made the process with which it was solved very obtuse. People just didn't get the sense that the problem was being taken care of. Due to that feeling, when January 1st came and went, many people dismissed y2k, and the work poured into making sure it wasn't an issue, as a hoax.
