I still wish I knew exactly what was said in the talk because as I've hinted there's such a wide range and I don't want to lay into the wrong thing. But anyway.
The basic problem with any philosophical position based on science is always the same: the science itself is subject to some level of change and revision, meaning that any conclusions reached no matter the strength of the philosophical argument are bound to be on shaky ground. Quantum Mechanics (QM) probably illustrates this problem better than anything else I can think og: essentially, any and all philosophies with some claim to originating from a scientific starting point are likely to be wholly wrong (and this is even before you start delving into the multiple interpretations of classical physics!); while the new physics itself has progressed markedly since any philosopher got their hands on it. Unless you are at or near the cutting edge of the subject you haven't got a chance to be even starting in the right place, let alone finishing there. This even applies to my own interpretation of the subject, for that matter, that I'm still having to think about how to word so I'll save that for another maxed-out AB post.
I suppose, though, that any attempt at "Quantum Philosophy" has to start at the point that a century of experiments has confirmed that the mathematical equations underlying the theory (most notably, the Schrodinger and Dirac Equations) are worth using and provide an accurate, if seriously bizarre, description of the world. Strictly speaking, though, these equations arguably don't actually describe the real world, so much as they describe the "square root" of it ("solutions" to QM equations must typically be squared in order to produce something you can actually observe and measure) -- and in a special way at that, introducing the square root of -1 (traditionally called the "imaginary unit") all over the place. Although by now I am used to this, when you step back for a moment it's seriously weird. i = sqrt(-1) got its name because when it was first discovered people didn't even accept the reality of it as a number. And yet, apparently, the real world insists upon something you can never directly see being at the very heart of how it works.
Perhaps it's all just a mathematical trick, that obscures how the world actually works. If so, then (perhaps a tad unfortunately) it's an incredibly successful trick.
But anyway, that's the mess we find ourselves in -- the Quantum world is by its very nature incredibly weird, but also incredibly true. Its truth has allowed us to progress unbelievably far in the last century of so; its weirdness opens the door for anyone and his dog to have a go at explaining it. In terms of mainstream scientific philosophy of QM, I personally have little time for the "many-worlds interpretation" (each time a "choice" has to be made, all events actually occur, spawning different worlds), which is just silly* but unfortunately rather popular particularly among spiritualists, I think. After all, if these other worlds in fact exist, their argument goes, we can communicate with them (look up "quantum jumping" as an example of this sort of crap).
The other key question, that I've given myself no room in this post to discuss, would be the question of the role of consciousness in quantum mechanics. Again, serious scientists have in the past given this idea (that consciousness plays a meaningful role in QM) credence; again, I think that's tosh; again, some people have jumped all over that and twisted it from scientific tosh to pseudoscientific tosh.
*then again, I suppose an interpretation I have more respect for but which involves communication travelling backwards in time is also pretty silly on the face of it...
