I was trying to get the Chrome team to understand this and implement a bookmark manager which took this into consideration. We have the compute power, the memory, and the understanding to build such a thing. Just a bookmark isn't useful. I want a snapshot of my mental map of how I got there, what it's about (auto summarization), other tabs I had open and their same histories, plus an easy way to pick that back up and dive in from that exact spot. I don't just want a saved session, but a place on a map of knowledge that I can jump back to. Then give me fuzzy search that can match the idea / meaning of something across these saves, so I can find it without remembering the URL or page title. Give me a topical timeline with a graph so I can see when I was thinking about something. The idea of a "bookmark" for a "page" on the web is cute and had a place in history, but we can do a lot better in 2017.
