I don't know where people get the idea that "flying cars" is a more noble achievement than "140 characters".

All these narratives you're repeating--you probably picked it up from some news article or tweet--is just another way people package their own agenda. What you're saying is equivalent to saying police is much more important than scientists. The truth is both are important and it's foolish to say one is more important than another.

Basically you're comparing apples to oranges and saying oranges are bad because the guy who sells apples started a well packaged propaganda to sell more apple and you believe it word for word.
