Here’s a LW site dev whining about the study, he was in it and i think he thinks it was unfair to AI

There a complete lack of introspection. It seems like the obvious conclusion to draw from a study showing people's subjective estimates of their productivity with LLMs were the exact opposite of right would inspire him to question his subjectively felt intuitions and experience but instead he doubles down and insists the study must be wrong and surely with the latest model and best use of it it would be a big improvement.
