# Key Technical and Conceptual Points from #hplusroadmap IRC Logs

• Nanoimprint lithography was discussed as a disruptive chip fabrication technology that could democratize ASIC production through cheaper, more distributed manufacturing models, with references to the homeCMOS project.

• Industrial cryogenic cutting applications were explored, particularly liquid nitrogen (LN2) technology being used commercially by companies like Nitrocision for slicing soft biopolymers.

• The conversation critiqued Ray Kurzweil's futurist works as derivative of extropian mailing list discussions, with recommendations to read more technically rigorous alternatives like "Nanosystems."

• Participants detailed historical DNA synthesis patent litigation from the 1990s, describing how Applied Biosystems used monopolistic practices like voiding warranties if customers purchased reagents from competitors.

• DIY microfluidics projects were discussed, including debates about toolpath generation approaches (SVG-to-toolpath conversion versus generating toolpaths directly from implicit geometry) and using Propeller microcontrollers for gantry systems.

• The group referenced work on code that generates SVG, DXF, and STEP files from functional representations (F-reps), suggesting approaches similar to ImplicitCAD for computational design.

• A philosophical exchange occurred around life extension, cryonics, and "deathism" (resignation to mortality), examining the distinction between continuous living versus preservation and revival.
