quite a bit of software you would need to understand the assembly. not everything is web-services.

I've found LLMs (since Opus 4.5) exceptionally good at reading and writing and debugging assembly.

Give them gdb/lldb and have your mind blown!

Do you mean gdb batch mode (which I've heard of others using with LLMs), or the LLM using gdb interactively ?

I've only needed assembly once in more than 20 years of programming, not a webdev

It was during university to get access to CPU counters for better instrumenting, like 15 years ago. Havent needed it since
