The problem is that ChatGPT is not capable of original ideas. When you see AI, you (and the bulk of the population) think Artificial Intelligence, but what you should be thinking is Assumed Intelligence.
If you open up a mobile phone keyboard and tap the next suggested word repeatedly, you're doing exactly the same as a large language model like ChatGPT, just much slower and with a tiny dataset.
And just like an autopredict keyboard can spout nonsense, so can ChatGPT. It's euphemistically called hallucinations, but really it's just grammatically correct gibberish.
It's just the current buzzword.
Hundreds if not thousands went before it and many more will follow.
Think of it as an in-built historic timestamp.
