Laws establish consequences when discovered, but discovery is the challenge. How can you mitigate the risk of someone recording with their phone? how can you tell who recorded it unless e.g. YC watermarks multicasts? What if that recording is never published but is distributed privately to/for someone else's advantage? Hackers putting together some of the more notable firetalks/skytalks this year had some adjacent conversations about creating possibly virtual-only firetalks, and these concerns were all raised given the traditionally ephemeral nature of in-person conversations at the events.
