Outside the verifiable domains I think the impact is more assistance/augmentation than outright disruption (i.e. a novelty which is still nice). A little tiny bit of value sprinkled over a very large user base but each person deriving little value overall.
Even as they use it as search it is at best an incrementable improvement on what they used to do - not life changing.
I have great faith in AI in e.g. medical equipment, or otherwise as something built in, working on a single problem in the background, but the chat interface is terrible.
The weekend slumps could equally suggest people are using it at work.
