Is GPT-4xyz better than the last one? I'm sure some benchmark numbers say that. But the number of applications where occasional hallucinations don't matter is very small, and where it matters nothing really changed. Companies are trying to use it for customer support but that predictably turned out to be a legal risk. Klarna went all-in on AI and regrets it now.

Some media are talking about Microsoft writing 30% of their new code with AI, but what Nadella actually said is less impressive: "maybe 20-30% of the code that is inside of our repos today in some of our projects are probably all written by software". Which, coincidentally, is the ratio of code that can be autocompleted by an IDE without LLM, according to Jetbrains.

I have yet to see any evidence that anything will change way faster than it ever has, aside from the readiness of many younger people to use it in everyday life for things it really shouldn't be used.
