Nobody is talking about when transmitters all switch off because, unlike other countries, the government doesn't control whether radio stations in the U.S. live or die. Will radio be completely streaming once the all existing radio listeners are on the lower side of the cemetery lawn and when? If I could tell you that for certain, I wouldn't be wasting my time on some radio discussion board.
I had an interesting AI discussion over a couple of beers with a very well-tech-connected friend the other evening. He thinks in ten years the public Internet isn't going to look anything like we experience today. He believes Google's (Alphabet) AI model 'Gemini'(tm), will be the default when you use Google Search, and it won't take you to sites on the Internet, but contained within Google itself. Duplicate that same model with Microsoft Bing(tm), or even shopping on Amazon. The algorithms want to control what options you see, and how you feel, and keep you dependent on their services. In other words, the Internet is no longer the Wild West of everything imaginable, but a few dominant players that control users' experiences through AI models serving up what you didn't know you wanted. Now take that to the next level and include news and entertainment choices. None of it is streamed on the Internet as we know today, but it is kept inside an ecosystem controlled by the major players.
What will that look like ten or twenty years from now, assuming the radio generation is gone? I have no clue.
