Wow,
I heard about them in the worst ways from the security/cryptography community, but the latest breaking-RSA farce led me to this article:

https://arstechnica.com/information-technology/2019/09/medicine-show-crown-sterling-demos-256-bit-rsa-key-cracking-at-private-event/

Money quote:
"The demonstration only raises more skepticism about Grant's work and about Crown Sterling's main thrust—an encryption product called Time AI that Grant claims will use the time signature of AI-generated music to generate "quantum-entangled" keys. "

Holly balls, this guy... *facepalm*
