# Key Points from #hplusroadmap IRC Discussions

• Kanzure was developing a Python/STEP library for parametric solid geometry and NURBS/bezier curves, with discussions highlighting the important distinction between true CAD software (which requires specific data structures for solid geometry) and 3D modeling tools like Blender.

• Historical context about transhumanism was provided by pmetzger, who created the original Extropians mailing list in 1991, sharing the seven principles of Extropianism: Perpetual Progress, Self-Transformation, Practical Optimism, Intelligent Technology, Open Society, Self-Direction, and Rational Thinking.

• Participants identified key challenges in the transhumanist movement, including excessive focus on discussion rather than building, political divisions, and conflicts between intellectual property interests versus practical implementation.

• Technical discussions covered computational challenges in molecular modeling, with calculations for nuclei positions in adamantane taking an hour on a laptop, highlighting the tension between using closed-source software for speed versus adhering to open-source principles.

• Open-source CAD and 3D modeling tools were evaluated, with recommendations for HeeksCAD, OpenSCAD, and Art of Illusion for RepRap 3D printer users, reflecting the community's interest in accessible tools for fabrication.

• A cosmology debate referenced WMAP data showing the universe is flat (within 1% error) and isotropic, supporting the conclusion that the universe is infinite, with references to Max Tegmark's work.

• Participants critiqued a recent H+ conference for low-quality presentations on post-singularity business models and outdated aging theories, while acknowledging the value of networking opportunities.
