Call me crazy, but I have literally no anxiety. As best I can tell, LLM's are basically good at BS'ing, in the technical sense of Harry G. Frankfurt's work: https://en.wikipedia.org/wiki/On_Bullshit

Now, there are certainly consequences, but given how awful the track record of predictions about "technology [x] will have consequence [y]" has been, I doubt we will be able to predict it, and there are many previous AI waves (remember IBM's Watson, that beat Ken Jennings at Jeopardy, and Deep Blue, that beat Kaspersky at chess?) which ended up impressing a lot of people and then having little impact. Perhaps this will end up accomplishing more. But, given how excellent it as at Harry Frankfurt's specific definition of BS, we should expect it to be better at impressing people than at doing anything else.
