# Key Points from #hplusroadmap IRC Discussion

• A paper on "Opportunities and challenges of a world with negligible senescence" was shared, examining the societal implications of radical life extension, published in Technological Forecasting and Social Change (October 2015).

• Multiple geoengineering approaches to climate change were discussed, including ocean iron fertilization, sulfate aerosol injection, weather control machines, and space-based solutions like sun shades and solettas.

• Someone proposed a decentralized AGI architecture combining a high-level virtual machine for thought with resilient networking inspired by filesharing and Bitcoin, where nodes would communicate via "sub-brain" transmission and use micropayments for network incentivization.

• The Open Tree of Life project (tree.opentreeoflife.org) was shared, which synthesizes phylogenetic knowledge into a comprehensive evolutionary tree, accompanied by a PNAS publication.

• A technical discussion about ephemeral Tor exit nodes revealed practical limitations, as directory authorities require time to validate exits, though such systems could still function as bridges for users facing censorship.

• The feasibility of nuclear pulse propulsion (Orion spacecraft) was critically examined in relation to international nuclear test ban treaties, with discussion of which countries might legally permit such development.
