Really not the same. Assembly / machine code is entirely deterministic - they are a notation for your thoughts. LLM produced content is more a smorgasbord of other people's thoughts, and cannot help you with clarity, conviction, etc etc.
However, I would strongly disagree that people are no longer writing/using assembly. I was writing a bit of assembly the other day, for example.
Come on over to the game emulation, reverse engineering, exploitation writing, CTF, malware analysis, etc. hobby spaces. Knowledge of assembly is absolutely mandatory to do essentially anything useful.
Here's another:

Given this, you might write less asm.
