Joel Spolsky in 2000:

The idea that new code is better than old is patently absurd. Old code has been used. It has been tested. Lots of bugs have been found, and they’ve been fixed. There’s nothing wrong with it. It doesn’t acquire bugs just by sitting around on your hard drive. Au contraire, baby! Is software supposed to be like an old Dodge Dart, that rusts just sitting in the garage? Is software like a teddy bear that’s kind of gross if it’s not made out of all new material?

This is lengthy, but right on. My second MacBook Pro’s logic board died after Catalina was released. I hated Catalina’s overzealous security, and Big Sur seems like an oversimplified yet buggy mess. I have unfortunately reached a point where, even with the release of Apple silicon Macs, I feel better off building a Windows PC. The OS was the reason for me to buy my first Mac; it’s now a reason to not buy my third.

El Paso definitely learns from its disasters. After the 2006 flood, they made huge drainage improvements. After the 2011 freeze (it got down to 12F/-21C in Las Cruces!), they made power station improvements. And as a result of drought, they have the largest inland desalination plant and implementing closed loop “advanced purification”. You love to see it.
