I want to understand where the seemingly arbitrary time frames come from.

"It's been 15 years. We should have completely fixed everything by now..."

Who says 15 years is long enough? I just don't get why right now is the time that certain things should be reality. The current rails predate many humans on the planet. Fiat predates all of us. Gold predates some civilizations as a money.

YouTube predates Bitcoin. Lol I remember YT not existing and I'm only 31. Most people didn't carry cell phones when I was a child. But yes, we should have already completely fixed money and broken governments with Bitcoin. In 15 years. What we have right now is astonishing for such a short period.
