This resonates so strongly with me.
I worked a job where I needed to use outdated Microsoft toolchains to build plugins for software, and the documentation was just -- gone. Good luck. I've been almost compulsively saving the things that feel important to me, while seldom browsing them for years -- all the while hunting for a faster and more intuitive recall system that lets me find them later.
My ex, however had a much more fluid relationship with the internet and media in general. They liked new things, and didn't particularly care if they enjoyed something and it faded into obscurity. I feel like that's the winning mentality, but I just can't bring myself to embrace it.
