Nothing against the article because it doesn't falsify any of the conclusions, but Moore's Law is often mis-stated. Moore said that we could double the number of components in an integrated circuit every 18-24 months, nothing more. It had nothing to do with cost or power, although he did dismiss the thermal energy argument in a sentence or two in the original paper.
The interesting issue has to do with Dennard's Law for power scaling, which said that power density would remain constant as we increased component density. This isn't true any more and that's part of the reason why multicore designs are the future (2 processors at 500MHz use less than one at 1GHz for a fully parallel workload).

I believe that such a large circuit can be built on a single wafer." In other words, it was the number of transistors that could economically be included in a single unit.
