The reality is that you will be left behind, you need to decide if thats a bad thing or not. If you want software development to be your career it probably is, if you enjoy it as a hobby than probably not. You're the 2020s version of the 1990s developer sticking with ASM.
This argument of LLMs vs manual coding being compared to higher level languages vs assembly really never holds well. To be honest people who know assembly are still definitely in demand for various open source projects as well as proprietary codebases in companies like within embedded systems, linux development, compiler engineering, etc. Whereas LLMs are a whole new class of problems and discussions with very little to almost no similarities
Yes, people who know ASM are in demand in a tiny very small portion of dev work. And even in most of their main areas like embedded a lot is moving to HLLs these days so even that is leaving but you don't hire asm devs to build your product anymore maybe a feature or something because they are just not productive enough.
When C and C++ came out we had a whole new class of problems too with people not using them correctly and over time best practices developed to make it safer and better quality. The same thing is happening today with LLMs.
