Or it might be that linear increase in intelligence requires exponentially more effort/thought to work through all the possible interactions and complexities needed to make it work. Instead of being exponential, we might end up stuck on a sub-linear trajectory forever, with breakthroughs and improvements less and less common, even with the help of superhuman intelligence. Really, assuming that the amount of intelligence you get out is linearly proportional to the amount you put in seems pretty silly, actually... its not like that works with adding programmers to a project.
The logistic curve looks exponential right up until it isn't.

Moot point if the logistic curve leads us well past the human-imaginable level of intelligence before reaching a zero with its cost/benefit differential.
