Being rules based isn't necessarily a bad thing or disingenuous. I develop healthcare AI products (ML/DL researcher) and we actually aim to be able to translate our models into a rules based engine (find a strong signal, interpret/understand model well enough to translate/embed into a rules engine, look for a new signal in our models, rinse + repeat). We end up deploying a mix of rules based and true ML based models into production but it may not be immediately obvious to the end user which type of model they are using.

I didn't mean it as being disingenuous - that's precisely the value that was sold and if you could do the proper "knowledge engineering", it worked well. It's just interesting to me having seen the previous turn of the AI hype wheel, how much is being repeated.

Another interesting thing was the transition from special purpose hardware - Lisp machines - to C code on commodity platforms. A contrast from today's ML moving in the other direction.

That's fair. Google's recent paper on predicting patient deaths is another good example of this (logistic regression + good feature engineering performed just as well as their deep learning models, and the logistic regression has the added benefit of being significantly more interpretable and as a result, actionable).

It'll be interesting to see when specialized ML focused silicon will become readily available. Right now I find ML libraries that are able to run on blended architectures (any combination of CPU and GPU's) much more exciting/impactful than TPU's. The ability to deploy on just about any cluster a customer may have available is huge.

As someone in the field, what do you think about the idea of a fully automated "doctor"?

Are we close to it being technically feasible , leaving aside regulation and interpersonal qualities doctors bring to the table ?

Depends on the definition of "doctor".

The likes of INTERNIST, CADUCEUS, and MYCIN have been around and provably accurate starting in the late 70s through the mid-80s. MYCIN even arguably sparked the 1st AI boom. But there were ethical issues with computer-aided diagnosis that I'm not sure have been solved/overcome.

Perhaps the current startup generation can get past them with Zuckerberg, Kalanick and Holmes as role models. :)
