Yes, and it doesn't matter.

Writing code in programming languages is a skill/necessity created by us to instruct computers what we want them to do

Initially in the 60s, this was done by connecting circuits one way or another (think ENIAC). Then we devised "programmable" computers and devised a bunch of codes (computer code instructions) that abstracted away those cables.

The we created Programming Languages to further abstract away the hardware complexity, and to be able to write down our wishes in a way that is more transferable between us humans, but that is still computable by machines.

But with LLMs and neural networks, at some point these abstractions wont be necessary.

The computers will still be making computations, but the way we tell them what we want is going to evolve.

It's fascinating.

Not to detract from your point, but there were software-programmable computers in the 50s. Check out Usagi Electric's videos about the Bendix G-15, where he loads software from punched tape.
