I believe that rather than it being a case of humans versus machines, the future of financial advice more likely lies somewhere in between, where human advisors leverage artificial intelligence and automation to become smarter and more efficient at doing their jobs. But to get there, they must change, and they must start now.
Given what we have learned from Advanced Chess, where humans and computers team up, your conjecture seems logical and likely. Even good, but not exceptional players, when they are trained to work well with their computer counterpart (which, itself, doesn’t even need to be the most powerful computer) can defeat the best-rated chess grandmasters using better computer.
This goes beyond just being able to give the best customer experience, but, also, delivering the best financial advice. With effective cooperation, a good financial advisor working with a good financial algorithm may be able to achieve better results than the best algorithm working alone. One of the main merits of advanced chess, as stated by its proponents is:
producing blunder-free games with the qualities and the beauty of both perfect tactical play and highly meaningful strategic plans
It is fair to say this applies to trading and investing as well.
I think it’s right that you say they must change, and start now. The change is learning what teamwork means when humans and machines work together for the best possible outcomes.
