A human plus a computer can solve far more problems than a human can alone. The combined system has super-human intelligence. Humans still offer contributions to problem solving that are quantitatively and qualitatively distinct from the areas that non-biological intelligence contributes. However, the fraction of problem solving that is contributed by non-biological intelligence is increasing, and there are no obvious boundaries that prevent non-biological intelligence from one day contributing the remaining fraction now contributed by humans.
We also have a growing class of humans who are so distant from the solutions they use to the current problems of life (technology) that these solutions are completely outside their ability to even understand, let alone contribute to.
We may expect these gradual trends to continue until humans, as slow, non-contributing consumers with zero understanding of the solutions they use, may be regarded as little more than venerated pets. Coddled, spoiled, taught to perform entertaining tricks, and shown-off. Better than extinction, right?
