It basically makes a person more efficient.

Instead of searching the web for hours and trying things, and eventually getting the result, you can ask chatGPT and get the result in seconds.

For example, you could write code in a language you've never used before in minutes using chatGPT, whereas it would take hours or days to do the same without it.

Having said that, as of today, the AI is still a bit limited, as in it only produces blocks of content. But you can put them together.

Same with a book for example, it can create maybe a page or even a chapter, but not the whole book yet.
