The old cliche is that we were promised flying cars but ended up with x where x is something trivial or mundane. Perhaps the best “x” is “140 characters”. This statement is meant to de-value the technologies developed in the last few decades. Instead of building grand things, we build trivialities. The irony is that x is often wildly popular and ubiquitous. x also generates a lot of profits and is likely to change behavior. Indeed, the flying car alternatives are almost always better ideas.
