Programming your own app is not practical. It's not worth the time. It's just easier to have someone else do it. I can probably write my own tax software using an LLM but there's no way I will spend the time to do it. It will probably cost me a few grand in tokens and I can't really know if it's accurate without taking lots of time to QA it. As programmers we've always been selling outcomes. No one accepts partially working code. It has to meet specifications. If a programmer can't do that then he/she loses their job. The programing profession is changing but it won't go away anytime soon.
