Witten and many others repeat it like a mantra: "it from qubit". This rallying cry of depressed theoreticians has never led to any tangible result. That is what all my friends and acquaintances told me since I can remember.
But isn't the spaghetti model a realization of the mantra? I hate to put such a loose idea as 'it from qubit' - and such a looser's idea, to be honest - in the neighborhood of the spaghetti model. But the analogy is striking. Is the basic principle of the spaghetti model a qubit?
Is Witten advertizing the spaghetti model?
