Truly excellent videos. I enjoyed the first one especially, even though the second one looks more professional.
I think any nonweird theory of the quantum world would be quite popular! But then, as is said in the videos, all theories must be nonlocal. I think the maths are basically models, approximations of what really happens. It helps us make predictions, but it doesn't really shows us what's going on, anymore than a curve on a chart shows us what obesity really looks like.
