I have a few years of experience in backend development, and I have realized that LLMs are incredible productivity boosts for generating code only if you know the underlying libraries/frameworks/languages very well. You can then prompt it with very specific instructions and it can go do that. Helps with the typing, but that's pretty much all. I still have to know everything and it can definitely not do everything on autopilot. I would be surprised if this product can do any real work.
