It's only a "major design smell" to "bounce back and forth" if it's computationally expensive. This theory makes it sound like electrons aren't firmly rooted in space and time to begin with.

Maybe it's computationally cheaper to define something as existing in all places and all times.

You can make it cheaper, but you have to accept a certain amount of uncertainty in your position and momentum data.

Don't forget the maximum speed, it'd be tough to simulate a universe where things could affect arbitrarily distant objects instantly!

Well I imagine it isn't optimized for readability :)

If the point is to have a jillion of electrons, each at the right time and place (for the observer), I assume a rather complicated mechanism must have been put in place to "tie the knot" just right - I mean to "navigate" the time-travelling electron just so it never fails to appear wherever, whenever it's expected.
