There's good reason to suspect that when AGI appears, it will quickly be developed to clearly super-human capabilities, just from the differences in capability between species that we are very closely related to. Bostrom and others makes an argument that the difference in intelligence between a person with extremely low IQ and extremely high IQ could be relatively very small related to the possible differences in intelligence/capability of various (hypothetical or actual) sentient entities. There's also the case of easy expansion in hardware or knowledge/learning resources once a software-based intelligent entity exists. E.g. if we're thinking of purely a speed difference in thinking, optimization by a significant factor could be possible purely by software optimization, and further still if specialized computing hardware is developed for the time-critical parts of the AI's processes. Ten PhDs working on a problem is clearly more formidable than one PhD working on a problem, even if they are all of equal intelligence.
