(1) Pointing out that Turing was well known before 2012, as if this fact somehow explains anything about the context or reasoning for the viewpoint, is lazy. Generally, duplicated points occur in internet forums. "someone else already said this" is, at best, banal.
(2) This is apparently what happened, so it's accurate critical analysis, afaict.
(3) This is beyond hyperbole. Fabric of society? Which society? What do you mean by "fabric"? SMH
Lastly, I am surprised at your umbrage at what I have said in (1). When asked "why", it seems like a pretty reasonable answer to say "look at all the other comments that confirm and justify this statement".
(3) Fair enough, it is hyperbolic. Democratic society. "Fabric" is a pretty common idiom for the underlying norms (e.g. journalism exposing issues with the other 3 branches, having a non-governmental source of mass information)
For what is worth, your comment and this link[1] is the first time I have seen it used for material infrastructure.
[1] I am on the fence whether the quotes in the link can straightforwardly be interpreted to be about material infrastructure as opposed to "moral/social fabric".
