    There's nothing "anti-realist" about relational or Bayesian subjective
interpretations, they just don't reify the wave function as you would like them to. Bohm used to make the same complaint that other theories weren't "realistic". Fuchs
    et al have as good an explanation of quantum computers as any dynamic 
    system, there's nothing special about computers - it's just not one that 
appeals to you.

Computers in particular, while not special, are good examples because they illustrate that nothing known in our universe (aside from the superposition) has the necessarily complexity to produce answers to certain complex problems.

But that's essentially everything, since everything is (presumably) quantum. But notice the limitation of quantum computers, if it has N qubits it takes 2^N complex numbers to specify its state, BUT you can only retrieve N bits of information from it (c.f. Holevo's theorem). So it doesn't really act like 2^N parallel computers.

    They say "don't ask" on fundamental questions, which is never a good 
attitude to
    have in science.

    That's your straw man attribution.  You've apparently stopped asking and 
decided you
    have the answer.

I would rather choose a speculative interpretation that turns out to be wrong then say QM needs no interpretation, nor should we look for one, as the paper you recently cited suggested.

    The sciences do not try to explain, they hardly even try to  interpret, 
they mainly
    make models. By a model is meant a  mathematical construct which, with the 
    of certain verbal  interpretations, describes observed phenomena. The 
    of  such a mathematical construct is solely and precisely that it is  
expected to work.

If Fuchs et al operated according to this quote, they would see that a model is not the same thing as the description/predictions of observed phenomena that it makes.

But it could be.  You only know the observations - you don't know the reality 
in itself.

If we identify reality only with observed phenomena, what is to prevent us from falling into solipsism or idealism?

Solipism doesn't seem to work well.  When I kick people they kick back.  :-)
