I've recently installed Dokuwiki on my NAS. It just stores your pages as markdown .txt files - so you can just use any text tools (editors/grep/sed whatever) on your pages if you want. The wiki interface also seems pretty minimal and very fast.

The fact that mining for cryptocurrency takes real resources doesn't make it a "store" of value. You take a whole bunch of electrical energy and turn it into bitcoin and entropy. You can't get that electrical energy back, and you're stuck with the massive amount of emissions that it causes. I also wouldn't view ordinary currency as a "store" of value - more an agreed representation of value. But where bitcoin pretty much only represents an amount of dollars agreed amongst people who buy bitcoin, ordinary currency (since it is generally used to purchase actual stuff) is a representation agreed amongst pretty much all the consumers and producers in the country or on the planet. Is there anyone that actually buys bitcoin for any other reason than the expectation that it's price will go up and they can make money (ie. actual dollars) on it?

That's an almost exact description of kotlin - Intellij pretty much literally found the most disliked bits of java and cleaned them up.
