Article is just a (wordy) recapitulation of this tweet from a former Walkman engineer: https://x.com/akiraa_tanaka/status/2080114490830680500

But fair play to OP, you'd have to bounce it through at least Google Translate to make it legible to the predominant English-speaking HM crowd: https://x-com.translate.goog/akiraa_tanaka/status/2080114490...

Still would have been good for the Substack author to link to the tweet rather than just embedding a nearly-too-small-to-be-readable png of a JPEG and six links to the tweet author's X profile.
