Contrast this "trade secret" to a chat with an Oxford don, and you'll find the don is quite straightforward in admitting they are fallible. Some admits are duds, and some are hits. Decisions are made based on a small amount of information, but only the dons decide what happens. They try hard to let in disadvantaged kids, but it's a crap shoot deciding who has potential and who doesn't. They rarely care about anything other than academics. (I'm not sure how they recruit the rowers.)
It's just laughable that an admissions process is a trade secret, and unless there's a compelling explanation given, I would assume they claim this because they are being sued by Asians about bias, and giving places to legacies, which is just as bad for a place that sells itself on excellence.

I'll submit that many, maybe even most, folks do not have these levels of creative aptitude. Moreover, the majority of creative output is crap to the majority of its consumers. I agree that the educational system is primarily ill-equipped to get people out of the current mentalities of employment, but I also think that there will be a certain, possibly large, subpopulation that doesn't have the aptitude or interest to do these sorts of things, even if there were such "magical training" to generate creative output that was valuable and desirable to most other people.
Even for the other fields he cited, like engineers, hedge-fund managers, etc., these currently require a high level of education and experience. No amount of training will reach the non-academically-inclined.
I think the future of people in the jobs that technology replaces is either to move to the direct service industry, which is much more difficult to automate and becomes more difficult to automate as the service level becomes higher, or abjectly falling out of the economy. Not everyone can paint or write a screenplay, and not everyone wants to.
I'm a workaholic as it is the only way to maintain my sanity.

Germany's national broadcaster Deutsche Welle produced an excellent documentary looking at the exact same scenario you described. [0]
It looked into the possibility of making short-haul transportation (focusing primarily on Hyperloop) virtually free with just one caveat: a precondition that users share all their private data that advertisers might find valuable -- free ride in exchange for ad-targetable data -- scary and intriguing at the same time.
