Nah, it says imagine that there is nothing that exists that is similar to being chatgpt.

That is, that chatgpt cannot _be_ because if it could there would in fact _be_ something that is like _being_ chatgpt.

Imagine we could prove that there is nothing it is like to be ChatGPT

You could rephrase it as "Imagine that we could prove that there is no existence equal to the existence of chatgpt"
