I recall hearing a lot of assembly engineers not wanting to let their skills rust either. They didn't want to be a "4th gen engineer" and have their skills replaced by proprietary compilers.

Same with folks who were used to ftp directly into prod and used folders instead of source control.

Look, I get it, it's frustrating to be really good at current tech and feel like the rug is getting pulled. I've been through a few cycles of all new shiny tools. It's always been better for me to embrace the new with a cheerful attitude. Being grumpy just makes people sour and leave the industry in a few years.
