Perhaps the reason why ChatGPT has become so popular is because it provides entertainment. So it is not a great leap forward in AI or a path to AGI, but instead a incredibly convoluted way of keeping reasonable intelligent people occupied and amused. You enter a prompt, and it returns a result - what a fun game!
Maybe that is it's primary contribution to society.
Increasingly now I use ChatGPT and sometimes Kagi. And they just work like I expect. I can think of one time that ChatGPT has failed me, which was when I was trying to remember the terms OLTP/OLAP in database architecture. But for a long time now it's been a very effective tool in my toolbox, while Google increasingly wears out.
