"Breakthroughs" are not really how synthetic intelligence has progressed so far. Look at speech recognition, for example. So far, that has mostly been a long, gradual slog. Maybe we are doing it wrong - and there is an easier way. However, that's not an isolated example - and if there are easier ways, we don't seem to be very good at finding them.

Of course, "breakthroughs" is a cumulative impression: now you don't know how to solve the problem or even how to state it, and 10 years later you do.

The idea of a "breakthrough" denotes a sudden leap forwards. There have been some of those.

One might cite back propagation, for example - but big breakthroughs seem rare, and most progress seems attributable to other factors - much as Robin Hanson claims happens in general: "in large systems most innovation value comes from many small innovations".
