The way articles are going they will be saying that a robot that punches buttons on a calculator [0] is artificial intelligence....

WOW PCA. That is some old ML right here. Last time I did PCA was for flows in an undergrad paper. It's been 15 years!

PCA was introduced in 1901. Who knew Karl Pearson was actually doing AI!

The image processing in a macaques brain has been doing PCA since way longer. Atleast according to [1], around 1hr36m in.

AI?!
This is just old school ML algorithm.

Well, AI is how we call machine learning these days. The deep neural networks we are using today are not exactly a new thing either (1960s), it is mostly just scaled up because we now have the hardware to do it.
AI is a vague term, ranging from simple game playing engines to humanlike sci-fi robots and godlike superintelligences. But now, most of the times, it just means machine learning.
