Just admit that you were wrong instead of this doubling down nonsense. LLMs are amazing at optimizing memory utilization. They have no problem obsessing over fitting as much data as possible onto a single cache line and micro benchmarking cache hits.
This seems like way too caustic of a reaction, OP is correct.
If you actually know what you're doing in $language, and you know how $language wants to emit the assembly or whatever, there's no huge advantage to just programming directly in assembly.
