I think it's fundamentally the difference between soft bullshit and hard calculations. Everyone can talk about AI, or linguistics, or statistics (or any complex field) in very general, undefined and bullshitty terms.
But what we need, and what the machine learning guys are bringing is hard calculation - 1 + 1 = 2 or input data, get features and make decisions well above human abilities.
My question to all the fringe folks: Where's the beef? What have they done? Where are the automatic cars built on Chomsky's theories? Where are the talking robots from the AGI? What methods have the SENS people got? Are the singularity folks just leeches off gullible rich people - selling them a future and taking their cash in the process without providing any real value?
