It’s highly probable that superintelligent AI is not possible at the same level of tech where general AI first becomes possible (this could even max out below human level if humans are not minimally intelligent to be general, which seems obviously true.). Said general AI would then have to improve in the same old manner as computer chip fabrication processes currently do, with a lot of time, effort, and research. Under this scenario, eventually your dichotomy might actually be the case for a while as tech improves.
