The article also paraphrases Reed saying, “Arguing that the nation could run out of spectrum is like saying it was going to run out of a color.” I explained to Brian Chen that spectrum is literally the exact same energy as light, not some far-fetched analogy. I explained that visible light is a subset of the electromagnetic spectrum. And that a frequency band is not *analogous* to a color, it is literally precisely the same electromagnetic energy as a color, only at a frequency that is outside of the capacity of our visual system. Some of this is captured in the 3.5 minute video that accompanies the article. The video also labels spectrum a public good. Yay!

Now a report published by the US Centers for Disease Control and Prevention shows that, despite this, the prevalence of ASD has continued to grow.
