#5: the thing that interested me most was the part that said

The infamous and problematic "measurement postulate" of quantum theory is not needed, since quantum superpositions necessarily localize through their interaction with classical spacetime.

Unless I've totally misunderstood, this sounds as if large superpositions wouldn't be stable – you can still do the thing with one electron and two slits, but nothing involving, say, a cat in a box is going to do anything weird.

So where's the boundary between those? In particular, what limit does it place on quantum computers?

Fascinating!

Hopefully someone will answer that soon!
