Maybe, but crypto currency in some form could see widespread use at some point. Perhaps it won't be Bitcoin, but the underlying technology. Turing's machines weren't directly used, but the principles he came up with impact us today.

I'm quite sure that his Enigma-like machines were used heavily and most enthusiastically.

The enigma machines were typewriter like devices of nazi manufacture designed to allow users to type clear text and produce cypher text that could be typed into devices that shared a secret to produce the original clear text.

Alan Turing is known for

- Being a primary figure in the effort to break the enigma machine code so that messages could be decoded without stealing the secret keys used. This was tactically valuable.

- Creating one of 2 mathematically equivalent logical models of computation eventually shown to be equivalent.

He is thus of pivotal importance in the development of modern computers, the defeat of the nazis, and codebreaking.

If you haven't heard of any of this it behooves you to read up a bit.

That is obviously what I'm referring to, what are you on about? It would behoove you to refrain from needlessly condescending replies.

I wasn't aware of any similarity between Turings Machines and the enigma machines. That's actually interesting thanks.

Did the original post say "his enigma machine" implying turings enigma machine? or did it say Enigma-"like" machine.

I certainly make enough typographical mistakes myself no particular shame in that.

The post that I responded to said "Turing's machines," I assume this didn't mean "Turing machines" because that's an abstract concept so what would it even mean for it to be "used directly?"

All I meant to say is that machines designed/built by Turing were in fact very, very useful in their time. I was too lazy about it though and should have looked up the name in the beginning.
