I'm actually wondering if people more just leave a billion tabs open versus using bookmarks at this point, like if bookmarks are becoming some kind of legacy feature at this point that Google will have removed from Chrome at some future point, and potentially just sell that feature as a new short-lived web service as if it's a new thing. If it became necessary if all browsers just ditched bookmarks entirely for some reason, I'll just use a text file or search through history, at least in the browsers that keep history more than a week. From what I can tell Chrome is not one of those, but that's not even my main browser anyway. I use at least a couple browsers to do different things depending on what's needed.
I come from an era of web browsing when it was more likely you'd just have one or maybe two windows open, not counting all the pop-up ads. Growing up with dial-up probably built that behavior as it would probably end up just being reading one thing while the next thing took a few minutes to load. I really only have tabs open in the low dozens if I'm doing some research on things at that moment and tend to keep things clean otherwise with maybe a few tabs open at most. I also tend to not have my desktop icons become a mess as well, but I also hardly open things from the desktop.
