In my opinion the bigger problem is, when people are not aware that they're in a bubble. They existed, even before social media and internet searches. E.G. when I was a kid/teen, I got most of the information about the world from one local news paper and one evening news show on tv. Yes, their "newsfeed" wasn't generated by algorithms. But still, it's someone that decided for me what is relevant and what not. Nowadays I have access to much more sources and different point of views as long as I am aware that they exist and know it's up to me looking them up. Similar thing if your part of a strongly opinionated subculture. It is hard to even realize how limited your horizon might be.

So I try to embrace the bubble when it is useful for me. I appreciate that when I type "something something python" into google the top results are relavant to my work and not about snakes or comedians. But when I'm want to form a politcal opinion I use duckduckgo and activly look for contrary positions.
