Only tangentially related, but I think it is very unfortunate that Everett's interpretation is called "Many Worlds". Talking about "Many Worlds" paints a picture of parallel universes that one can travel between. That makes no sense, and it is not what Everett says.

I was introduced to quantum mechanics from a TCS point of view, i.e. via quantum computing. After some time of getting used to the mathematics, it seemed quite natural to me to suppose that the universe "really is" a vector in a Hilbert space, without any spontaneous collapses, and so on. This actually caused me to reject the notion that there are "Many Worlds". After all, it's all just components of a single vector describing our universe. It's a single world that just happens to work according to rules that are unintuitive relative to our everyday experience (and the real mystery lies in how consciousness works, but that's a mystery even without QM).

So I was really surprised when I found out that what was meant by "Many Worlds" is almost exactly how I had interpreted things as well, and to this day it feels to me as if the name as an attempt to popularize this interpretation dilutes a proper understanding.
