It was in response to the implication that it would be nice if all the new companies that big businesses acquire have everything (like ipv6) "ready to go" upon acquisition.
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.
This is just about as close to how I handle most note taking currently.
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. :)
It's a roll-your-own solution, but tt-rss has been an exceedingly great replacement for Reader when it closed down. (And as long as RSS exists, I never have to worry about my service going away.)
