A "bullshit sandwich" if you will.
When one tells people this we get the reply "but so do random blogs! or reddit comments!". Well yes, but they're just random blogs and reddit comments, often peppered with syntactic and spelling mistakes, non sequiturs, and other absurdities. Nobody would take them seriously.
ChatGPT is very different. It doesn't say "this random redditor says this, and this other random redditor says the exact opposite, so IDK, I'm just a machine, please make up your mind".
What it says is "this is the absolute truth that I, a 'large language model', have been able to extract from the vast amount of information I have been trained on. You can rely on it with confidence."
I'm sorry to sound hyperbolic but this cannot end well.
