Maybe it's just my ADHD, but I can't even imagine managing that many tabs.
In my workflow, I start a project, then keep opening new tabs as I need to look things up, frequently moving tabs between multiple browsers spanning my 32" monitor. So long as I'm working on that problem, I just keep opening new tabs.
Then, when I've finally squared away the section of the project I was working on, I usually just close the browser entirely and start fresh.
Needing to manually sift through the 80+ tabs I chaotically opened in the last hour or so to figure out what's worth keeping? Hell no. That's what browser history is for. It's Etch-a-Sketch time! Shake it clean and start fresh.
Whereas my ADHD has me keeping huge numbers of tabs open (although my record is only ~350) because once it's closed, it's completely gone from my mind. Bookmarks are a burial ground, and history has all the other stuff that I don't need to reference anymore. With tabs, I can go through them and remember why I kept it around, and close it once I've actually done something with it.
