> computers after work is a bad thing; people can have families and other hobbies?

No not bad per se, but it did clearly show that, without on the job courses, why all of them are stuck in the early 2000s tech wise.

Some people start with a company and get lucky with early success and then get restricted because of that success: get new clients via existing, everyone likes it and asks for new features and without noticing it you might find yourself 15 years down the road with ancient tech and no one understanding anything current. Then you can still thrive if your clients like it... we have similar clients: a 1980s factory, another 1980s factory, a logistics app from the 1990s etc. Things deeply ingrained in some vertical, expensive but better priced than the SAPs etc of this world so it keeps going and going.
