Right, except there's a problem, everywhere and everyone that matters in the world of technology disagrees with you from IBM to Apple, from Facebook to Google, from Microsoft to Oracle, from MIT to Cambridge, from Harvard to Berkley, from Tim Berners Lee to Mark Zuckerberg, from Sandy Pentland to Bill Gates, from Peter Norvig to Larry Page.
So on one hand we have some random guy on Slashdot claiming it doesn't exist, and on the other we have the who's who of technology companies, universities, technologists, professors saying it does.
You'll have to excuse me therefore if I can't help but think that what you're actually saying is "I've no idea what the fuck data science is, so I'm going to pretend it doesn't exist and that it's stupid". Your argument doesn't even make sense, you recognise statistics is a specialisation of mathematics and claim that's okay, but specialisations of other subjects are apparently not, yet you can't elaborate why, or even where or how you drawn the line. You claim it's just statistics, but then statistics doesn't tell us how to gather, store, manage, and work with massive data sets, data sets so large we're on the cutting edge of figuring out how to deal with them, something that requires research, you know, like science.
Well, good luck with that but if you hadn't noticed there's a lot of people making use of it in both positive and negative ways, from large scale healthcare research, to selling us as products, to the NSA profiling us on our data. It's probably not something that you should pretend just doesn't exist, because it kind of has profound implications for our lives today, and going forward.
