Decades? We are talking here about 2-3 years lag due to conservatist approach. You seem to know nothing about what you write.

You think the core systems of major airlines or any other large org turnover every 2-3 years? You think knowing the syntax of a particular language is comparable to decades of domain knowledge? You think that ANY 20-something, anywhere in the world, has decades of experience of anything??

No, YOU know nothing about what you write.
