history - Programming Concepts That Were "Automated" By Modern Languages -

There is a strange question but here it is. What are "automated" programming concepts by modern languages? What I mean is that you had to manually make those concepts first, here's an example: I have just read that in C, you collect garbage manually; Although with "modern" languages, the compiler / interpreter / language itself takes care of it. Do you know about someone else or nobody else?

For the longest, hand was necessary to do this. Now most compilers can make it infinitely better than any human.

Note: It is not to say that hand-adaptation has not yet been completed, as is the comments. I am just saying that many adaptations that are done by hand are now automated.
