It's much better than most other brief explanations I've read. One thing I wish it would hit more strongly is that the "actual world" is bigger than what we can interact with, we only experience a "slice" of this larger world under almost all circumstances- The complex amplitudes of qbits hint at this fact, and quantum computers essentially take advantage of this "extra stuff in the world" to do calculations, though in a completely different manner than mere "parallel computation". What we don't yet know is if this "extra stuff" is really big (i.e. represents parallel universes) or is just some kind of more restricted phenomenon. The other important thing to know is that our brains are subject to the same complex probability amplitudes as qbits- That's why things seem weird when we magnify quantum phenomena via experiments and try to explain what's happening: Our brains get entangled with the experiment and the "slice" of the world that we're experiencing varies depending on the results of the experiment. Quantum phenomena seem a lot less "weird" once you get comfortable with this fact: i.e. that our brains are just physical objects prone to the exact same physical laws as elementary particles, and that the organ we're using to reason about the experiment with is entangled with the experiment itself.
