It's an interesting thing about standards... once something starts a certain way it will remain that way forever. Yes, QWERTY keyboards were actually a downgrade from Dvorak because people could type so fast the swing arms would collide with each other and get stuck. IBM fixed that problem in the 1950s with the "Selectric" typewriter which used that rotating ball and therefore didn't jam. Yet, the public was used to the keyboard. I'm in the US, and we're still on the British imperial measurement system, but other things are still in use that aren't in their optimal form. Bicycle seats are derivatives of horse saddles, and well designed ergonomic seats are just not standard. Cars (short for carriages) are modified horse carts, most prop planes have their propellers up front instead of in a pusher configuration, and most planes use conventional tails instead of canards, helicopters use anti-torque tail rotors instead of bleed air or stacked rotors, and our "spaceships" of 3304 use glass windows and don't even have 1960s era autopilots, and still use the Christian calendar instead of restarting a new one. It's fun.
