- Discussion of whether an open-source DNA microarray synthesizer (POSAM-like device) could be built with an Opentrons liquid-handling robot; participants weighed the need for picoliter-scale piezoelectric nozzles against the larger volumes delivered by standard micropipettes and concluded that Opentrons could be adapted but would sacrifice ultra-low-volume precision.  
- Docl proposed a “lab-on-a-chip server farm” model: massively parallel microfluidic chips running spiroligomer-catalyst discovery experiments, with results automatically submitted to a public-domain molecular database and rewarded via a Bitcoin-style micropayment scheme to incentivize open-source chemical exploration.  
- Practical obstacles to at-home DNA synthesis were enumerated: phosphoramidite monomers cost ~US $5 g⁻¹, each base addition consumes ~2 mg, and reagents such as acetic anhydride and MeCN are moisture-sensitive and degrade quickly, making cartridge-style “printer” supplies difficult to implement.  
- Neuralink’s job posting for an “Implant Embedded & Firmware Engineer” specifying C/C++ proficiency sparked debate about the safety of using C++ in brain-implant firmware; Rust and Ada were suggested as safer alternatives, followed by a broader discussion of compile-time guarantees, language complexity, and Rust’s improving compilation speed.  
- Scott Locklin’s blog post “RNA memory hypothesis” (https://scottlocklin.wordpress.com/2021/02/03/rna-memory-hypothesis/) was shared as an intriguing but controversial idea, with participants noting the large body of contrary evidence yet acknowledging its conceptual appeal.
