If we're talking about triggering an exponentially self-improving lineage of intelligences/computers, then they will either hit a wall fairly quickly (in the grand scheme) or face increasing practical constraints that flatten the curve. The limit may be at an unfathomably high level compared to where we stand, but it will come fast. That's unless, say, it turns out the universe can adapt its physics to meet certain types of ever-increasing demands.
