• A proposal was floated to create Watson-Crick-pairing “vinyl polymer analogues of nucleic acids” by grafting nucleobase-like hydrogen-bonding groups onto isotactic polystyrene chains, yielding a synthetic scaffold that can still hybridize to natural DNA or RNA.  
• A simpler variant suggested replacing one carbon on the phenyl ring with nitrogen, yielding Poly(4-vinylpyridine) as a ready-made, commercially available polymer that could serve the same recognition role without custom synthesis.  
• A 1977 paper on vinyl-polymer nucleic-acid mimics (doi:10.1016/0032-3861(77)90156-2, linked via Sci-Hub) was offered as prior art supporting the feasibility of such synthetic base-pairing polymers.  
• Discussion of “bitrot” on Twitter and Google Drive highlighted the silent loss of decade-old user accounts and corrupted files, underscoring the principle that “backups are incomplete and non-functional until recovery has been demonstrated.”  
• A South China Morning Post article (shared via .t bot) reported that Biden and Xi were expected to pledge a mutual ban on AI control of autonomous weapons and nuclear warhead systems; participants quickly noted the pledge would be unverifiable without intrusive inspections.
