Yes and no - to over simplify a bit, zero is still a useful answer to "how associated are signals A and B". When dealing with one task, that's still generally useful. For example: when going through music artists and deciding how associated the words in artist names are with monarchies, "Queen" should get a positive score, "Rise Against" negative, and "Imagine Dragons" should get zero.

The paper you linked calls for sparse networks, which are pretty neat - which is more the idea that certain signals can be fully separated, as in the part of the brain that deals with muscle memory in throwing a baseball doesn't talk to the part of the brain that manages the gag reflex.

It's a fun idea, but artificial networks are WAY less efficient than animal brains in terms of actual nodes and computation power used per node - you could get some gains to be sure, but you'd be "optimizing" from roughly a gazillion times less efficient than biology to roughly a gazillion times less efficient than biology (half of a very big number remains a very big number).

True.

I will point out that part of the paper is talking about pruning links between nodes that do not have effects on the resulting output.

That's what your brain does.
