I think you are mixing up things here. I am talking about principles on how to solve tasks in programming, you are talking about differences in programming languages. But the thing is: what is right in programming was the same in C 40 years ago and is exactly still the same if you use Erlang. And it is also the reason why many old programs still work because previous generations applied the basic principles much more diligent than we do (because there is the next NodeJS around the corer, etc. smirking)
