Its been a while since I studied Davies's arguments, but I remembered
thinking at the time that what Davies was proposing was in
contradiction with standard QM, hence amenable to experimental
falsification.

Not that there aren't enough discussions going on already, I wanted to know 
what people think about Paul Davies' argument using Seth Lloyd's 
calculations, concluding that a quantum computer can never be built?  I 
suppose there are people here that believe that the multiverse makes the 
quantum computer possible regardless of what Davies says, but if so, why?


Here's a post that sums up some of it and provides some links:

Some quick criticisms of Davies' argument can be found in the comments of 
this blog entry by a physicist working on quantum computation:

By the way, the belief vs. knowledge and G/G* gap and naming issue is 
very interesting to me, but I am still in the process of thinking about 
it some more...

Or, perhaps we are indeed living in a Bostromian simulation. QM is used at
the microscopic scale of the simulation, and for computational economy GR is
used for macroscopic modelling (stars and planets and satellites and
Buicks). While both are true descriptions of reality (in that the simulation
does actually utilize them as in model), they are in actuality incompatible.
There *is* no unified theory, and we will never develop a successful theory
of quantum gravity because there isn't one; the microscopic and macroscopic
run on different rules.
