Too Long; Didn't Read
The more novel and revolutionary a technology, the harder it is to give it a description that will do it justice. Remember, for example, how long it took you to grok blockchains? I personally had to read a handful of articles before even coming close to grokking them. And I’ve observed this same explanation barrier when describing blockchains to friends: noticing my early failure, I’d qualify my explanation with, “You need to understand computer science to get it,” — a helpful trick if you don’t want to be the only one who feels incompetent at the end of a difficult explanation.
