Please ELI5, I lost track. I used to learn a bit of C and a bit of Python a few years ago but never really went deeper into programming. And now suddenly it seems that a host of new programming languages have appeared and that stuff that used to work fine in whatever old language it was in is now rewritten in a new language.
How do languages like Golang and Rust differ from older languages (these two have probably been around a while but for me they feel 'new')? Why are we coming up with new languages all the time? Besides those two, what other languages are there worth knowing about? Is it worth learning them? Are they going to come up with yet another one next week? (I know, many questions, an invitation to infodump I guess ...)
EDIT: A deep reaching, long and detailed history of some programming languages, for the future passerby:
Uh, sometimes people just feel like “I could do it better” so they make a language or they’re in a CSci course that focused on writing a compiler/interpretter and so it started as coursework and just grew.
But yeah, others have mentioned that languages often come about because doing a thing in that language could’ve been done better so another took form.
