>Humans are tool builders. But they don't always build useful tools ! And more notably, useful tools don't necessarily become widespread, and widespread tools aren't necessarily useful And of course widespread tooling is often not actually best-in-class But so human advancement is not sufficient reasoning -- it's not uncommon that doing nothing at all is more optimal than doing the thing we did (eg the recent flight boarding article on frontpage, which described the common back-to-front, and front-to-back, load orders being worse than random load -- the optimal solution is quite convoluted)
