Speaking only for myself, I have found that using an LLM has allowed me to add significant utility to the apps that I ship.

I am not thrilled with all the coding decisions that it makes. I would definitely do stuff differently, but I have learned not to pop the hood and mess with the engine, myself. If I really don't like something, I ask the LLM to change it.

It's worked for me, but YMMV. I'm just one guy, shipping relatively small apps.
