Oh, haha. I’d read that and incorrectly inferred a sardonic reference to the “evergreen” browsers and their endless upgrade treadmill.
But, nope, not a metaphor, an actual treadmill.
I didn't even consider that! But certainly there's a ring to the term "Treadmill Browser".
Technogym Run 700, the one I see at my gym. They have a multi language setup including chinese, Japanese, and Korean, and that's as far as glyphes seem to go.
