Technically, the future does not have to be so gloomy. Soon the IA may built for itself the better tools we failed to build (or adopt). One can expect centralised intelligence to surpass collective intelligence, after all.
I would say it's debatable whether centralised intelligence can outperform collective intelligence. Centralised intelligence can be very efficient, but by definition it will lack the perspectives that a diverse collective intelligence can offer. In the long run, if the search for global optima is the ultimate goal, a diverse collective intelligence will have a higher chance of success than a centralised intelligence, especially in multidimensional spaces.
