Why should it dismiss satire?
Gemini is already caught on toxic talking positivity. In real life, there are also many people that don't understand 2nd degree talking. It takes time to learn to recognize it and I'm sure Gem will learn quick, not sure for most humans though.
It's role is not to invent things--or just modify them from its own perspective--but to report them and deliver the best way possible, as summary or report.
There will always be situations people don't understand, even smart ones not only stupids. So, do you want Google to teach what is the "truth"--its truth--, or help to find the right information?
Make people learn and understand is a far more difficult matter. This is for me the big issue. Before there was religion and beliefs, now there is marketing and content production. Otherwise nothing new under the sun.
