IBM's sub-nanometer chip gets skepticism on commercialization

IBM announced a sub-1 nanometer chip technology and the HN thread immediately asked the same question twice: how does this become a product? Commenters noted that IBM regularly announces silicon breakthroughs but they rarely reach commercial fabs. The actual question of whether IBM licenses to TSMC or Samsung, or whether this stays in a research lab, went mostly unanswered.

One commenter raised a terminology nitpick about whether 'angstrom node' is the right framing versus picometer, which actually points at a broader issue: chip node naming has become marketing language disconnected from physical dimensions, and even technically literate people can't agree on what the numbers mean.

For founders building hardware or depending on chip roadmaps, IBM research announcements are interesting but not actionable on any near-term timeline.
