This assumes that the thing that should be held constant is complexity, and that the loadtimes will therefore decrease. On the contrary, loadtime itself is the thing being held (more or less) constant, and the complexity is the (increasing) variable.

Progress is not being able to do faster the same things we used to do, but to be able to do more in the same amount of time.

These seem to be equivalent, but they're not, because the first is merely additive, but the second is multiplicative.
