I think to most (90+%?) software developers out their in the world, Assembler might as well be hieroglyphics. They/we can guess at the concepts involved of course, but actually being able to read the code end to end, and have a mental model of what is happening is not really going to happen. Not without some sort of Rosetta Stone. (Comments :) )

I think 2075 developers will feel the same way about modern Java, C#, TypeScript, etc.

They will think of themselves as software developers but they won't be writing code the same way, they'll be giving guided instructions to much higher level tools (perhaps AIs that themselves have a provenance back to modern LLMs)

Just as today there will still be those that need to write low level critical code. There are still lots of people today that have to write Assembler, though end up expressing it via C or Rust. And there will be people still working on AI technology. But even those will be built off other AI's.
