The deep learning boom caught almost everyone by surprise

I think there is a slight disconnect here between making AI systems which are smart and AI systems which are useful. It’s a very old fallacy in AI: pretending tools which assist human intelligence by solving human problems must themselves be intelligent.

The utility of big datasets was indeed surprising, but that skepticism came about from recognizing the scaling paradigm must be a dead end: vertebrates across the board require less data to learn new things, by several orders of magnitude. Methods to give ANNs “common sense” are essentially identical to the old LISP expert systems: hard-wiring the answers to specific common-sense questions in either code or training data, even though fish and lizards can rapidly make common-sense deductions about manmade objects they couldn’t have possibly seen in their evolutionary histories. Even spiders have generalization abilities seemingly absent in transformers: they spin webs inside human homes with unnatural geometry.

Again it is surprising that the ImageNet stuff worked as well as it did. Deep learning is undoubtedly a useful way to build applications, just like Lisp was. But I think we are about as close to AGI as we were in the 80s, since we have made zero progress on common sense: in the 80s we knew Big Data can poorly emulate common sense, and that’s where we’re at today.

Sometimes I wonder if it’s fair to say this.

Organisms have had billions of years of training. We might come online and succeed in our environments with very little data, but we can’t ignore the information that’s been trained into our DNA, so to speak.

What’s billions of years of sensory information that drove behavior and selection, if not training data?
