1. They probably are. I'm sure I would notice a 500% increase in the rate that products get better, but I'm also sure I wouldn't notice 10%, which is much more realistic (but imo it's probably still less.) 2. Productivity gains don't go directly to products getting better. Individual developers may choose to realize some gains by spending more time with their family. Of course the company will claw that back but it takes time. And when they do, some of the gains may instead be realized by higher profit margins rather than better products and it will take time for consumers try to claw that back using their market choices. 3. Companies have lots of moving parts and a speed they're used to going; it will take time to adjust if one part goes a little faster. 4. LLM-assistants help a lot with getting up to speed in a new field or making stuff from scratch, and a lot less for a skilled team who already knows all the product code and surrounding tools. So "products you use regularly" benefit the least.
