I can't imagine 147 tabs. I have 9 pinned tabs and maybe ... 6 other tabs open if I'm particularly busy. I also turn off my work laptop at the end of the day, because all of my state is restored when this handful of tabs comes back.

Maybe this is just me managing my ADHD, but when I see people with hundreds of tabs open I just can't imagine how they work. Every tab has been mashed down to its favicon and I watch them struggle to find the right one. It seems insane to me.
