For me as a computer scientist with interest in medicine (using Deep Learning to beat humans in detecting diseases), this was a cool finding pointing to a possible algorithmic reason behind schizophrenia. Now it might be just a small part of the puzzle, intertwined with other mechanisms we don't understand with overly complex interactions, not mentioning it likely misses other, completely different diagnoses sharing the same label.

So yes, your questions are perfectly adequate, though for me personally that finding is exciting, as I can potentially apply supercomputing on that problem.
