Here Harris is right on. There is no reason to conclude from QM that the universe is fundamentally Mind. QM is indeed mysterious and counter-intuitive in many ways, but Idealism is not the necessary consequence of this. As Harris points out, 'measurement' does not invoke Mind per say, it only invokes measurement.
Now, there are strange things in QM, mainly non-separability, which is genuinely strange, but that doesn't mean we have to smoke doobies and try to use The Force.
Additionally, Harris points out that the Mind is still dependant upon the physical processes within the body, and, as much as I find Penrose an interesting read, it is not obvious that QM gets us anywhere when it comes to solving the PHILOSOPHICAL problem of Mind.
