To me the most complicated thing in every project is the business knowledge. It's the tribal knowledge like "do not send null in this endpoint" or what happens when a request A will be send after B was sent to C and the mercury was in conjunction with venus on an odd day of march (answer: everything would explode). And LLM are solving 20% of my work, while the other things are talking to people, inventing new tests etc. I wonder btw. why the LLM bubble created problems on developers' hiring market. Were those companies thinking that LLM will write the code on its own?
