# Summary of IRC Discussion on April 11, 2016

• A discussion about brain emulation and sleep explored whether emulated minds would need to sleep, with participants noting that if emulation time is computationally expensive, a significant portion of resources would be wasted on emulating sleep states - essentially creating a "sleep tax."

• Participants debated whether emulated minds could run at different speeds during sleep periods versus awake periods, with some suggesting this might be possible but limited by the need to synchronize with others and by fundamental computational constraints.

• Robin Hanson's upcoming book "Age of Em" was referenced, particularly around the 48-minute mark of a YouTube presentation where he discusses emulation economics and potential class systems in a world of uploaded minds.

• Participants discussed the computational requirements for brain emulation, noting that while we can establish upper physical limits (like total energy of known galaxies), we have no clear understanding of the level of detail needed to properly emulate consciousness.

• A brief discussion of asteroid mining companies like Deep Space Industries and Planetary Resources suggested that asteroid mining is considered a plausible future industry by some participants.

• A link was shared to an IEET article by Giulio Prisco about transhumanism and related topics.
