How does ChatGPT seem to know so much?
You will learn in plain words how ChatGPT learned so many things.
ChatGPT learned by reading a huge amount of text. Think of countless books, articles, and websites.
From all that reading, it learned how words fit together. So it can answer on many topics.
It does not "know" things the way a person does. It is very good at putting helpful words in order.
That is why it can be wrong sometimes. It learned patterns, not perfect truth. So important facts still need a check.

Buddy says
It is wide but not always deep. Use it to learn, then confirm the important parts.
