This is simple: I don't know which slit the photon/electron is going to go
through and I can't find out. I have to send more than one photon/electron
towards the slits to make sure they go through, they are likely to go through
both. All this says to me is that interference between photons and electrons
isn't effected by time. If I send them through one at a time I get
interference from the one I haven't sent through yet, but I still have to
send through both slits at some point in time.
Am I missing something?

Too late.

P.S. Just to add to the weirdness (you enjoy it really). If at some point we
prove that Everett theory is true, the universe will split into two (or more)
realities, one where the theory is true (this one) and one where it is not.
Because in the other reality the theory is not true, our reality cannot
exist! So as soon as we consciously observe the existence of many worlds,
those many worlds will collapse leaving only one!
