In my experience, education certainly seems to not have kept up with computing, at least in terms of having massive academic-industry partnerships like a doctors residency or a trade apprenticeship .
I’d definitely agree that it is probably harder to become good in older organizations - the technologies are probably generations behind the current state of the art and the learning curves are high for those older technologies.
Just thinking through keyboard, but it’s probably reaching the point where enterprises need to evaluate aqui-hire or outsourcing entire development departments due to attrition, due to the incentives to leave for regular employees.
