I suspect we are not orders of magnitudes more intelligent than some of our cetacean friends in the deep sea. At the end of the day, all the achievements you've listed are not only the result of massive intelligence but opposable-thumb hands (for tool use and writing) and fire (for an easy early source of energy to runaway with). If humans were just as intelligent but never had these, we'd never reach the moon or build machines.
