Well right now it's just another website you have to go to with intent to use it like ChatGPT, but if Google built it into search it would get a ton of organic use from people doing things like googling error messages.

I'm not sure if this is what is planned of course, but that would be far more widely used than an otherwise siloed website you have to visit specifically.

Also remember that most people have at least never used ChatGPT, and most probably still haven't heard of it. We live in a tech bubble – none of my family had heard of it a few weeks ago. They all use Google search on a daily basis.
