I've come to the same conclusion: If you just want a huge volume of code written as fast as possible, and don't care about 1. how big it is, 2. how fast it runs, 3. how buggy it is, 4. how maintainable or understandable it is, or 5. the overall craftsmanship and artistry of it, then you're probably seeing huge productivity gains! And this is fine for a lot of people and for a lot of companies: Quality really doesn't matter. They just care about shitting out mediocre code as fast as possible.
If you do care about these things, it will take you overall longer to write the code with an LLM than it would by hand-crafting it. I started playing around with Claude on my hobby projects, and found it requires an enormous amount of exhausting handholding and post-processing to get the code to the point where I am really happy with it as a consistent, complete, expressive work of art that I would be willing to sign my name to.
