Put another way though, the failure rate was decreased from 0.6 to 0.57 or a 5% reduction. That's pretty significant. If you can reduce LASIK failure rate by 5%, that would provide a ton of value although you would be talking about an absolute improvement of 0.001% in success rate.

I agree that the improvements we are seeing are increasingly due to simply spending more time/money/power but that quip is probably the weakest argument. I would have liked to have seen a Fermi calculation where the power used during training is only 1% (or probably much less) of the total power used. The other thing that reeks naivety is basically the world takes a lot of compute. Much more money and compute is wasted on Candy Crush for instance.
