What's the GOAT programming language right now?

Assembly

Methinks you have confused the terms OG and GOAT, which are not at all synonymous. OG means "original", which is not a subjective qualifier that will change with time and public opinion.

Scratch

Python

Lua

Someone should make a GOAT programing language and call it GOAT

C

Perl
