Ok : define Intelligence. Define Life.

There are no accepted definitions of these terms. Are they meaningless?

AI that does not include backpropagation or logical deduction or GA's or optimisation is... is... magical thinking. AI without the nuts and bolts from the last 50 years of work is meaningless. The article is heartfelt, and we all agree with the tenant that people pretending that they are using AI when they are really using a database isn't a good thing, but if you take any current system look right down inside it all you will find is a Shannon type implementation of church-turing.

There are tonnes of other approaches to machine learning that don't involve backprop! There are also other approaches to neural netwroks that don't use backprop (have a look at Numenta's stuff for example). I suggest you watch Pat Winston's brilliant MIT AI lectures to see how huge the range of techniques is.

I direct you to lectures 12a and 12b.
