After the Accelerating Change Conference, John Smart and I were debating the merits of spending on better bandwidth vs spending on more CPU power. He noted that bandwidth efficiency is growing more slowly than compute power or storage and argued it was natural. I said that the money spent on the next chip fab would be better spent buying out TV broadcasters and using their spectrum for bits. There are regulatory reasons why that is difficult, but Kevin Werbach shows the value of doing so and how to get there.
