Will there be a sequel?
In that sense the story title is slightly misleading because the idea of a "step" implies a 1-D function that goes up suddenly, while my mental model of intelligence is more similar to a multi-dimensional space, where each axis is a type of computation. When you're putting things on faster hardware you're moving yourself upwards along all axes, but when you add a type of computation (e.g. Mystery module) you're introducing a new axis, capturing a wider volume of cognitive ability. In that sense the title is alluding to a cognitive step on the 1-D function of the total volume, not of any individual axis of it. Okay, maybe this needs vigorous hand-waving and/or a whiteboard to communicate properly, I'm sorry :)
