> For instance, the QWERTY keyboard layout exists to prevent typewriter keys from jamming, but we're stuck with it because it's the "standardized solution" and you can't really buy a non-QWERTY keyboard without getting into the enthusiast market.

So, we are "stuck" with something that apparently seems to work fine for most people, and when it doesn't there is an option to also use something else?

Not sure if that's a great example

Sometimes good enough is just good enough
