One of the things that most annoys me about computing circa 2017 - which has kinda always been true but I hoped it would get better, and it hasn't - is that we have a serious lack of truly fundamental, correct concepts.
Information is almost literal thought-stuff. Costs a bit of energy, space, time, yes, but compared to bricks, it's like magic super-Lego. Almost anything we can imagine, we can create.
But we've created a vast tangled web we can't really understand. Didn't mean to. Just did.
