I do not see much relevance here. Bitcoin and RADIO radios are quite different, why compare them to each other? . Thanks!
If you read the article you will see that it says that Bitcoin and radios are the exact same thing. It does not use radio adoption as a mere example, it says that Bitcoin uses radio waves for transmitting music.
You're both missing the point.
Bitcoin to radio isn't the right analogy. It's the blockchain that has so much in common with radio as it does the combustible engine, the refrigerator, the television set, the airplane, the printing press, and the internet. It's a new technology, it's adoption will be slow at first and then booming because it takes time to generate the momentum of the people and the use cases for folks to realize how valuable it is, as a technology.
