It's not "garbage" it called science & mathematics, those terms have "meaning", and have lead to progress in hard long-standing problems, which have in turn lead to billions of dollars and millions of man-hours allocated to understanding and using them.

Just because you lack ability to understand nuances of something does not makes it "garbage".

Respectfully, I believe the "garbage" to which yarou was referring to was not the algorithms, but simply to the data that is being fed into these algorithms.

The point being that, no matter how sophisticated these techniques are, the quality of the results is constrained by the quality of the input data.

As Charles Babbage said: "On two occasions I have been asked, 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question."
