Ok and they were wrong, but now people are right that it is great at coding.

If something gets better over time, it is definitionally true that it was bad for every case in the past until it becomes good. But then it is good.

Thats how that works. For everything. You are talking in tautologies while not understanding the implication of your arguments and how it applies to very general things like "A thing that improves over time".
