Depends how loosely we interpret this. Do we mean online AI language models which are part of a continuous lineage tracing back to the present chatGPT will not have revolutionized anything, or do we mean that OpenAI and their product line known as chatGPT in particular will not have revolutionized anything? Let's disambiguate now so no one says we are equivocating in 5 years. I'm understanding it to mean the former.

I mean the latter. Science progresses with big steps every now and then so it would be crazy for me to claim "AI will never exist". It's clear that eventually we'll get there.

It's a fact that somebody somewhere thought of making better bearings for their horse-pulled carriages centuries ago. That person does not get credit for modern cars' suspension systems however.
