A point that I always try bring up is that adding more mining capacity shifts the distribution of coins but it doesn't change the rate of mining at all. Ideally you'd have the compute power be tiny amounts divided up over a large number of people. But that would require everyone participating to be principled and using Bitcoin because of its decentralized nature instead of as a way to make money. Human nature would never let that happen.
