Define "professional."
I write stuff for free. It's definitely "professional grade," and lots of people use the stuff I ship, but I don't earn anything for it.
I use AI every day, but I don't think that it is in the way that people here use it.
I use it as a "coding partner" (chat interface).
It has accelerated my work 100X. The quality seems OK. I have had to learn to step back, and let the LLM write stuff the way that it wants, but if I do that, and perform minimal changes to what it gives me, the results are great.
