Things have been accelerating in a sigmoidal manner, which looks exponential in the early curve, but then plateaus as it approaches a limit. It's hard to say how far along we in the curve now, but given that we're bumping up against the limits of silicon semiconductors now, I'd say perhaps farther than you might expect.
