Talk:Church–Turing–Deutsch principle

Untitled
This all seems fairly questionable. See for example hypercomputation, real computation. Linking to a blog is, well, less than authoritative.

It seems to me that this is just the strong Church-Turing thesis. I also wonder where Deutsch comes into this, because he was born after Turing died! A google search didn't seem to yield anything called "Church-Turing-Deutsch" outside of that blog and wikipedia. Unless there's something I'm missing, maybe this page should just redirect to Church-Turing thesis? --Superninja 06:30, 15 Aug 2004 (UTC)

A quick lookup on google scholar returned [], indicating that the original paper was published in "Proceedings of the Royal Society of London" A 400, pp. 99-117. I don't have access to that resource just now, but perhaps someone could check whether the paper really was published there and whether M. Nielsen summarized it correctly (because, seemingly, this article has been derived from his blog entry). --141.26.64.5 11:01, 30 Nov 2004 (UTC)

The blog entry is now unreachable
Trying to look up the external reference now reveals a broken link.

Merge proposal
I think that this article should be merged with Church–Turing thesis, which already discusses the so-called Physical Church-Turing Thesis. The term "Church–Turing–Deutsch_principle" should not be used if there is no source for it; Deutsch's own articles do not employ this term (naturally!). AmirOnWiki (talk) 00:21, 9 January 2013 (UTC)
 * I support merging... For whatever it matters, ~8 years after the proposal was made. · · · Omnissiahs hierophant (talk) 11:32, 20 November 2021 (UTC)

This article could be replaced with a redirect to Simulation hypothesis. If no one tells me that i should not do that within a month, then i will replace the page with a redirect, and also rephrase all 20-or-so links to this page. This talk page is just full of arguments against this article existing, and no counter-arguments. · · · Omnissiahs hierophant (talk) 12:02, 20 November 2021 (UTC)


 * This article has little or nothing to do with the simulation hypothesis, which is a hypothesis that Deutsch actually opposes in his book The Beginning of Infinity. The simulation hypothesis says that our universe is literally a simulation (whatever that means), whereas the physical Church-Turing principle is a proposed constraint on the types of physical laws that our universe obeys (the laws can be simulated on a Turing machine).
 * I would support merging into with Church-Turing thesis, but not redirecting to Simulation hypothesis. 24.49.8.99 (talk) 18:08, 22 March 2022 (UTC)
