I've been realizing lately that we're already to the point where LLMs can basically take written English language and create the computer code it's describing. I think in the future perhaps most (and eventually all) software can be written basically the way we write method/function documentation today. You describe a function, give it a name, describe it's inputs/output arguments. And with enough specificity there will be a [perfect] function that can be written (multiple of course actually) which accomplishes what's described. So we can create entire applications this way. I guess this is already being called no-code or low-code systems, but I think perhaps as a universal language where instructions MUST be given, perhaps LISP is indeed the best because anyone can learn the syntax in basically a couple of minutes.

I can't see how, in 100 years (or maybe even just 50) humans will still need more than ONE computer programming language. Or at the most two. We might always need C++ to exist for low level stuff, but we only need ONE higher level language.
