Interesting that you believe your subjective experience outweighs the claims of all others who report successfully using LLMs for coding. Wouldn't a more charitable interpretation be that it doesn't fit the stuff you're doing?
Regardless, I do wonder how accurate those successful reports are. Do people take LLM output, use it verbatim, not notice subtle bugs, and report that as success?
There's a big difference between "I've seen X" and "I've not seen X". The latter does not invalidate the former, unless you believe the person is lying or being delusional.
