It takes time to research and publish. It'll always be some slightly old model. Is this argument just a permanent get out of jail free card? Add 10 to each year, will we be seeing that said in the future?
however, productivity is sensitive to the model, and models have significantly improved in the last 1.5-2 years. sometimes things move quickly and research gets outdated. ai is not the first field where this has happened.
the research is still valuable, it just has to be acknowledged that it is specific to a point in time. using it for an argument 2 years later just shows that the leah is being intellectually dishonest, and it weakens the overall message.
