We can see what consumers do. The Gemini app is second most downloaded app for the iPhone, right behind OpenAI. Apple is certainly not trying to "distort the picture" as you evidently wish to believe that Google is doing.

That's hardly an indication that actual "non-technical" consumers don't care, or that there is any sort of barrier to either using both apps or using whichever is better at the moment, or whichever is more helpful in generating the meme of the moment.

If it were actually true that OpenAI was "plenty good enough" for 99% of questions that people have, and that "there is no reason to switch" then OpenAI could just stop training new models, which is absurdly expensive. They aren't doing that, because they sensibly believe that having better models matters to consumers.
