A better way to phrase it is: The birth of the internet (1969) is closer to the birth of television (1927) than it is to today.
If you think about it, every tech is just radio. And I don’t just mean cellular, wifi, and bluetooth, There are few things on an SoC that aren’t just refinements and miniaturizations of radio tech.
It’s all based on the same mathematical model. And since it’s not profitable to make real progress in technology when you’re already making money from it, it’s all a very similar concept of the same technology. Capitalism sure is swell 🙃
While it’s true that the internet is technically a closer peer of radio and TV, I think OP is right to focus on the web.
The web and email are the internet’s main public applications. They’re governed by open formats and protocols, just like the underlying internet is. In order to publish or to send, you don’t need permission from anyone. That is not the case with social media or mobile OSs, which generally use closed-source software or proprietary protocols or both.
It’s no coincidence that social platforms come and go but the web is still there, or that the “w” in the name is now generally spelled in lowercase just as happened with the “i” in Internet. Open standards always win in the end.
