bastage
I was making a "joke" that it's as likely as us getting to another planet and it being already setup to be habitable by humans.
When Google Reader went away I looked at a few of the hosted alternatives but found tt-rss early on and never looked back.
You can't beat computers for quick searching and Onenote is both "GUI" enough to be friendly to people I have to share with and also does all those other things you mention. (Plus a lot of other cool stuff.)
I also use Sublime/vim in a similar way you mention, although I tend to use that as "RAM" in the sense that I don't save my snippets -- if they're not important enough to document elsewhere then if something really bad were to happen where (at least in Sublime) if a non-saved tab didn't show up at start automatically "oh well". (I've never had that happen though.)
Where I'm failing lately is any kind of physical pen/paper note taking since just the feel of that is great so I've added that into my TODO's of 2017. :)
For every pro in any solution there's usually a similarly weighted con, both of which need to be balanced against the users technical ability, requirements, "infrastructure", etc.
There's no such thing as a silver bullet, but it's what makes the game fun.
