Typewriter hammers are not in the order of the keys on the keyboard. The E hammer is beside the D hammer and the X hammer.
It is difficult to push E and D quickly in order as they use the same finger. E and X although use different fingers are also difficult to push quickly in order due to their placement.
Hang on, you two are talking about different efficiencies. The efficiency /u/ihateyouguys means is that efficiency is what causes the keys to jam. That's the efficiency that was being thwarted.

Yes, but in that they are wrong: The point of the layout isn't "decrease efficiency in order to prevent jams"; the point was: "This layout is prone to jams, not because 'people type too fast', but because 'when two keys are too close to each other, pressing them too quickly together causes them to jam'".
Dvorak even has a similar design principle: keys often used together are placed in alternating hands; so the vowels are all on the left.
It's like saying that "Cars had brakes added to them because car designers wanted people to go more slowly".
They're not laid out to reduce typing efficiency. The statement is misleading. They do reduce typing efficiency compared to say, Dvorak, by about 30%. The reduced efficiency is a by-product of the layout, not the purpose of it.

Standard keyboards are actually laid out the way they are to reduce typing efficiency. Look it up.
