Very interesting article.

It is correct that there are superluminal effects in physics, but so far none of them allows to transmit any information. If I set up an entangled pair of particles, I keep one and I send the second to someone in another galaxy. If I measure later, that immediately gives me information on the far away particle.
The problem is that I can in no way influence what I will measure, so I cannot send information to the person in the other galaxy.

I completely see the concerns of bitcoin quantum security. I also understand the idea of quantum law, but this problem seems to be purely philosophical. Am I missing something?
