    It is not the case that Church-Turing thesis revisions historically follow from theoretical separations, not from physical realizability—as Deutsch's 1985 argument itself demonstrates.

    ?Set your confidence on the premises below to see your aggregate.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Deutsch's argument gained traction only because quantum mechanics was already physically realized; theory alone wouldn't have motivated revision.
      ?

      Think about whether this reason is strong or weak

    • 2.CTT revisions historically responded to *discovered* computational phenomena (non-halting, interactive systems), which empirical practice revealed first.
      ?

      Think about whether this reason is strong or weak

    • 3.Separating 'theoretical' from 'physical' obscures that all formal systems abstract from physical substrate—the distinction is methodological, not ontological.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Deutsch's quantum computing argument was purely theoretical—no quantum computer existed in 1985, yet it motivated thesis revisions.
      ?

      Think about whether this reason is strong or weak

    • 2.Historical CTT revisions (oracle machines, interactive computation) arose from abstract mathematical analysis, not engineering breakthroughs.
      ?

      Think about whether this reason is strong or weak

    • 3.Physical realizability is contingent on engineering; theoretical separations reveal fundamental logical boundaries independent of technology.
      ?

      Think about whether this reason is strong or weak
