I would love for that ability to be easily determined visually, and easily toggled on/off. A big "personalized" and "generic" toggle switch at the top would be useful.

I don't think the ability to serve up specialized content is the concern here. It is the fragmentation that results when we no longer have a shared reality or a consistent set of results in the population. Results specific to any one person is terrifying in some of its implications.

That's how you create bubbles.

part of the issue with 'bubbles', as I see it, is that you don't know you're in a bubble. a big huge honking option of "keep me in the bubble" and "show results outside my bubble" would make it a lot more obvious (and manageable) to many people who are oblivious to the notion that they live in an information bubble. won't stop people who only use one source of news, but in a search aspect, it would be useful.

Interestingly, Google themselves seem to be at least somewhat aware of this - though it may just be an accidental side effect of trying to drive user engagement on YouTube.

I’ve been noticing an occasional “Show me something new to me” prompt showing up in my YT feed. It has literally never provided anything I was interested in watching, but I appreciate that they’re trying to burst bubbles.

Youtube sometimes recommends that, but if you scroll the topics bar all the way to the right, you can access it at any time.

Any time I use a Google product, I know I'm in a bubble.

"Everyone should get the same search results." is really just rightspeak for "Everyone should be in my bubble."

Not all bubbles are harmful. I’m in a regional bubble when I search for “restaurant”. I’m in a programming language bubble when I search for coding issues.

Tune it to be less bubbly with controversial topics, perhaps.
