i have never used an AI customer service chat that was more helpful than the previous deterministic chat bots that regurgitate the FAQ or whatever.
ChatGPT was released to the public four years ago and today i can't think of a single software feature or product that uses it that i would miss if it disappeared today.
@peter gee and it's been getting smarter all the time too, four solid years of exponential something or other, and so little to show for it
