I would say "yes" to that. But fortunately, with the load being so widely distributed, the load on our "local" quantum computers would effectively be zero (ie. x/inf). Unless, of course, our universe is the oddball and most others are running at full capacity. That's a depressing possibility.
The load could be zero, it could be infinite, or anywhere in between. Infinite universes sending infinite work is inf/inf. It's not possible to know if that's going to tend towards something like 0 or something like positive infinity without having some way to measure. But it's an error to just assume it's zero.
I completely agree. I was thinking it highly unlikely that other universes would be operating at full efficiency, so the average would more on the zero side. But, yeah, that's not how infinities work I suppose :) Still, I'm enjoying thinking about it.
