I think you mean talker. Walker would be things that actually did stuff - you know like search, translation, locomotion or prediction. That's a lot of words and a lot of books in a bunch of the soft sciences (linguistics and politics) which are highly susceptible to class A bullshit. All of that doesn't mean anything - no different from Richard Dawkins who irritates me in a similar fashion - I ask once again - where's the beef?

I still don't see Chomsky robots walking around, Chomsky translation translating my text to French or Chomsky AI driving cars. Nope - all Google/IBM/Microsoft/DARPA/Boston Dynamics/etc. AKA Hard science-engineers utilising statistics, not soft science blowhards.
As somebody who used to do a bit of NLP work in the dim and distant past I can testify that Chomsky's work on context free grammars, etc. (certainly used to anyway - not been poking at it for about fifteen years now) got applied a fuck of a lot.
The model probably doesn't have a great deal of relation to what happens inside folks heads - but it was stupidly useful for making computers do stuff though. Might be better techniques now - I don't know. But saying that it wasn't applicable practical work is basically ignoring the NLP stuff that was happening in the 80's and 90's.
(let alone the more obvious useful stuff for us geeky folk - the formal grammar stuff we use and think about for compilers. Chomsky Hierarchy, etc.)
And, I'm not enough of a historian of science to know, but it seems to me that the basic results Chomsky proved on Regular Languages and CFGs paved the way for the Hidden Markov Models (HMMs) that have been so effective in language understanding. Basically, the HMMs are the natural probabilistic extension of Regular Languages.
I'm not sure if Viterbi and the other developers of the basic HMM toolkit were directly influenced by Chomsky, or if state machines were just in the air. Certainly Chomsky's basic work in the late 1950s predated Viterbi's work in the 1960s.
If your definition of real science is something that has good prediction/application potential, that's a rather unusual definition of science. Are mathematicians, theoretical physicists all talk as well ?
Mathematicians aren't - you can prove their correctness over abstract planes and use them to for example run a hedge fund or a software company into trillions of revenue when making testable predictions in macro reality.
Theoretical physicists that use mathematics to make testable predictions are too. You can use them to also make electric engines, statistical extractors and accurate physical simulations that are corroborated with empirical evidence.
If the prediction is not testable, is unfalsifiable, is unreproducible, is not independent and is not supported by overwhelming evidence - it is bullshit - no ifs, buts or ands.
Better let Andrew Wiles know his 8 years spent on Fermat's Last Theorem was just a bullshit waste of time, because he couldn't use it to run a hedge fund, or software company...
It can only be 'proved' in the 'contrived' world of pure mathematics... what bullshit!
No, you provided a qualification of why they weren't... I gave you an example of a mathematician who broke your qualification, and logically should fall into your definition of a 'quack'.
The idea being, that you'd have to back pedal, and change your qualification. Which I could then use to apply to other fields, that you deem as 'quackery', and thus undo the foundation of your argument.
Instead, you just denied the reality of what you said... I didn't count on that. Well done.
Chomsky's a pretty substantial walker.
