I haven’t used Google as a primary search engine in a decade or more. Nothing I do depends on Gemini (I don’t even use Apple Intelligence that’s a Gemini white label).
Personally, I think what Gemini is destroying is a market-based financial model that many came to associate with the Internet, information access and lifestyle.
Most of the websites I visit pre-date Google and some have gone as far as blocking all bots via robots.txt. They survive not via predatory ad networks but by donations and volunteers.
It’s why I like Lemmy; it follows the same model.
