> At least from what I have seen it is a massive productivity boost for coding and general research

Are companies release more software with less developers? If the answer is no, then the productivity has not improved. It might SEEM like it improves because you're able to produce more code and you spend less time programming, but that might not be the case in actuality.

From what I've seen, AI is very good and very popular but it hasn't improved programming productivity in a meaningful way. The bottlenecks are unchanged so writing more code faster doesn't help anything. A lot of companies let a lot of employees go due to AI, and their product velocity has noticably gone down and their quality is noticably worse.
