Atomically precise mechanosynthesis of carbon structures on hydrogenated Silicon

At the current time I see this is front page and has reasonable upvotes, but not one comment. My guess is that this is highly useful for either: * Building chips (but it's on a silicon surface, not with silicon) * Carbon nanotubes (looking forward to a space elevator, folks, one day ;)) * It's a more notable movement forward in nano construction in general and I just know too little to understand its impact. Given the zero comments to date: would someone who knows this area like to accept an invitation to share something really interesting about this paper, please? :)

This seems to be the galena cat whisker stage of developing Drexler's "eutactic chemistry". It may be a parlor trick forever, or it might be the humble beginnings of mechanosynthesis, the first working tool-tips for a Drexler arm. https://wiki.reprap.org/wiki/Drexler_Arm

Off-topic, these days information just goes in circles from subreddits, X, YouTube, and Hacker News to countless secondary sources, and then back again to the same original sources.

On my cork board I'll paste this up and run a red string to https://arxiv.org/abs/2605.05914 and put a post-it between them with COMPUTONIUM???? written on it Can we please keep it together for a modest number of decades longer please.
