Self-reported productivity does not equate to actual productivity. People have all sorts of biases that make such assessments fairly pointless. They only gauge how you feel about your productivity, which is not necessarily a bad thing, but it doesn't mean you're actually more productive.

To extend on this, the measures of productivity before LLMs were difficult for any kind of complex work, so there's no reason to think we would have better measures now.

You need broad economic measurements, not individual or company specific. And that takes a long time plus there's a lot of noise in the data right now (war, for example).
