This is such a strawman. Do you have to really stoop to this level? There are a billion useless things people pay for, is that a measure of the intelligence behind it? People routinely pay $1000 dollars for a dog, does that mean a dog is 50x more intelligent than ChatGPT? All I'm saying is that we should be a bit more humble about intelligence when we understand so little about it.
Just because LLMs are useful, it doesn't mean they exhibit more intelligence than a mouse. A mouse probably also doesn't reason about anything, but it is an agent capable of independent behavior, something that is still very far removed from current AI models.
