That's not an effect of all humans on average, it's an effect on a few people who finally have a chance to take advantage of these tools.
I heard in a YouTube interview a physicist saying that LLMs are helping physics research just because any physicist out there can now ask graduate-level questions about currently published papers, that is, have access to knowledge that would have been hard to come by before, sharing knowledge across sub-domains of physics by asking ChatGPT.
