Is The Concept Of 'Fahrenheit 451' Flawed And Outdated?

I read Fahrenheit 451 in middle school, the plot is basically that books are illegal and citizens are only allowed to watch TV. The reason books were illegal is because "anyone could make a book, but not anyone could make a TV series". So to control what the population is exposed to they banned books.

But the thing is, with modern technology such as smartphones and YouTube, anyone "CAN " make a TV series.

The book was written in the year 1953, so I don't think the author back then even imagined smartphones or YouTube would ever be invented.
