I have friends who make such 50x productivity claims. They are correct if we define productivity as creating untested apps and games and their features that will never ship --- or be purchased, even if they were to ship. Thus, “productivity” has become just another point of contention.
100% agree. There are far more half-baked, incomplete "products" and projects out there now that it is easier to generate code. Generously, that doesn't necessarily equate to productivity.
I've agree with the fact that the last 10% of a project is the hardest part, and that's the part that Gen-AI sucks at (hell, maybe the 30%).
