I had lunch this week with some former coworkers.
When I'd started working with them it was on the 20 year old C++ engine that ran everything.
Even at that time there was large team 'rewriting' it in Java. That team was dissolved about 2 years later.
During the course of my employment two more large teams were spun up to do a rewrite and then came crashing down after a year or two.
I hadn't seen my coworkers for about 7 years. Naturally they were still working on the C++ code. Naturally they'd seen two more rewrite teams come and go while I'd been gone.
I'm not sure why I'm bringing this up......
