Agreed. The article gives a good primer on how CAPTCHAs work, how basic versions of them used to be easily solve-able, and how / why a general-purpose solution - like this is described to be - would be amazing ... and a bit of background on how such a solution would be similar to human "processing" anyway. What the article doesn't describe is any detail of how it works. Then again ... the creators of such a revolutionary technology, if true, would want to keep it protected in various ways, not to mention out of adversaries' hands (adversaries = spammers, criminals, other companies, other researchers).
