# Key Points from ##hplusroadmap IRC Discussion (Nov 29, 2014)

• A crowdfunding campaign for "brain backups" was critically discussed, highlighting the gap between optimistic marketing claims about future brain downloading capabilities and technical reality.

• Participants shared innovative DIY approaches to advanced scientific equipment, including a low-cost Atomic Force Microscope design using DVD components and piezoelectric elements, with discussion of probe costs (€390-400 for 5-15 chips).

• A Minecraft simulation of a neuron was shared that used block stacks to represent sodium and potassium ions, demonstrating action potentials and neurotransmitter binding sites as an educational model.

• The group discussed Cambrian Genomics' $10M funding for DNA printing technology and their accelerator program, which included a company developing printed viruses targeting microbes that cause vaginal infections.

• Advanced materials research was shared, including a direct laser writing technique for creating nanodiamond films from graphite under ambient conditions and DNA brick crystals capable of displaying precise three-dimensional nanoscale features.

• The Nengo software platform was highlighted for implementing biologically realistic neural models capable of performing cognitive, perceptual, and motor tasks using the Neural Engineering Framework.

• Participants noted the remarkable price drop in computing hardware, with quad-core tablets available for as little as $40, making powerful computing increasingly accessible for DIY projects.

• The conversation included critical discussion of Whole Brain Emulation research, particularly criticizing reliance on Kurzweil's MRI resolution trend extrapolations without addressing fundamental physical limitations.
