I disagree. There is no interference pattern because it’s just one electron. But there is interference, and the electron will hit the screen only in a spot that corresponds to an interference maximum. That the electron might not land along its classical trajectory (i.e. not the m=0 location) is IMO remarkable. And yes, this experiment has been done, in showing that the interference pattern shows up after repeated single electrons passing through the double slit.
