I really don’t think that’s true at all. ChatGPT is absolutely not mainstream. It’s pierced the consciousness of the tech-savvy, which maybe be our world, but is decidedly not mainstream. Most people would have no idea how to even use it, they hear about it from headlines. Having it in your pocket and interacting with it on a near-daily basis would be that mainstream moment, whether Apple gets there this year or Google manages to get that feature in tens of millions of phones through an update to its essential services through the Play Store. But your comment definitely shows what it means to be in a bubble.
