Everyone is talking about ChatGPT. Your neighbor uses it. Your boss uses it. Your aunt uses it to write birthday cards now. So what is actually going on here?
ChatGPT is a text prediction tool. You type something, it predicts what a helpful response looks like. That is really it. No brain inside. No wizard behind a curtain. The system operates on word probability. It does not think. It calculates the most likely next word in a sequence.
Ask it to write a cover letter at 11pm and it will not complain. That alone makes it worth knowing.
It can be wrong. Confidently, professionally, impressively wrong. This is called a hallucination, which is a fancy word for "it made that up and had no idea."
Common problem areas include:
Use it for drafts, ideas, and the boring stuff you hate doing.
Always remember to use it as a first draft.
Always check anything really important with a trusted human before committing to a course of action.
This goes for ChatGPT and every other AI tool out there, not just this one.
Do not trust any AI with legal, medical, or financial questions without verifying the answer somewhere else. A real professional still matters.
It is a useful tool. Just not an all-knowing one.
