This is called "rationalization", and to be honest, it looks worse than you may realize.

The inference-based methods in AI qre more likely to he of the "probabilistic graphical models" variety (there are already marriages of Bayesian and Deep Learning techniques), and less likely to be of the "first order predicate calculus" variety. We humans don't have a particularly strong logical inference engine either - unless properly trained, people make the silliest logical mistakes and arrive at wrong conclusions all the time.

That's not an example of genius by any stretch of imagination, sorry.

Sensitivity and recall are two names for the same thing, Mr Stats 101 :)

Also, please explain the problem with using ROC here. The probabilistic interpretation of ROC's AUC is the probability of correctly ranking a random mixed pair (i.e. ranking the positive example higher than a negative one). How is that metric affected by the 80/20 split of the test data? Genuinely curios here...

Ever heard of the halting problem?

"Less bad" and "equally bad" are incompatible statements, you're claiming both are true

Same with Armenian: I can read and understand 5th century texts simply as an educated native speaker. It probably has to do with how much the culture relies on its written texts (because there are spoken dialects of Armenian that I dom't understand at all, while having no trouble with the written dialect from 1500 years ago)

What kind of company do you work for?

> 1. Steve Jobs was a couple of standard deviations better at this than almost anyone

This is a statistical oxymoron.

It matters very much in computational / quant finance

I don't know, wouldn't be so sure without actual supporting data.

Anecdotally I know many talented people who got "broken" at high school level (due to any number of issues, from poverty to physical and emotional trauma). Having connections, mentors, initial capital, educated family, it all helps a lot.

This is not US-specific either, I made it to the US from a war-torn country across the globe with no money or connections, but I am extremely stubborn. There were definitely people who didn't make it this far who arguably had the pure IQ advantage.
