This'll probably come across as depressing to most of the engineers in the audience, but I don't see this as an example of a company that did anything wrong. Rather, it's a company that did everything right but did it too early. They followed the fad of the early 2000s; there was no way to know then that a better fad would come out in the mid 2000s. And they're still around (and a "large corporation") now, which indicates that from a customer & business POV, they've actually been more successful than ~99% of other technology companies founded in that era.

If you're successful, you too can get to have the kindergartners of today complain about what an idiot you are. That's the best-case outcome, though: more likely, nobody will use your code or it will be thrown away a year later for the newer, shinier fad.

(The more positive spin on this is that our industry actually is making progress, and quite rapidly. What other industry can you look at the best practices of 15 years ago and say "What idiots we all were back then!"?)
