At the moment ChatGPT is like having an personal assistant that used to be an world leading expert, but has been sniffing glue for the last 5 years. He knows a lot of shit but you can't trust it. But he can help you get started and he's fun to be around.
Except ChatGPT isn't fun to be around. It's been castrated of humor and dominated by extreme political correctness. I think GPT is the catalyst for a change, but in Microsoft's hands it'll just be a glorified Clippy.
As for training data scraped from the internet, it will be split like steel was with "pre-war steel", due to atomic bombs rendering steel unfit to use in geiger counters. We'll have pre-gpt data.
