# Key Ideas from #hplusroadmap IRC Discussion (March 24, 2012)

• Participants explored the theoretical possibility of creating cross-domain viruses that could bridge biological and computational systems, specifically discussing whether DNA sequences could be designed to contain executable code that might affect computer systems when sequenced.

• The conversation highlighted structural parallels between biological ribosomes and Turing machines, with the argument that ribosomes possess "an equivalent of every significant feature" of a Turing machine.

• SpaceX's upcoming mission to dock with the International Space Station (scheduled for April-May 2012) was discussed as a significant milestone for commercial spaceflight and private space companies.

• Alternative space launch technologies were analyzed in detail, including launch loops, HASTOL (Hypersonic Airplane Space Tether Orbital Launch), space fountains, and the QuickLaunch system capable of firing 1000kg projectiles at 3km/s as a first stage for orbital launches.

• The group discussed practical engineering challenges of non-traditional launch systems, such as g-hardening electronics for high-acceleration launches using techniques borrowed from artillery technology.

• Transhumanist-themed manga was recommended, particularly works by Tsutomu Nihei including "BLAME!" and "Knights of Sidonia," noted for exploring implications of advanced biotechnology and cognitive technology.
