That's a bit condescending. Twilio and similar services may not be of obvious use to everyone, for example. However, once I explained what it could be used for (and the recent patio11 Twilio presentation helps), most of my friends, while perhaps not needing it, grokked why I was interested. Some saw the utility for their own projects, as well. A more useful response would be to explain what you would use this for and why it might better/different than other solutions. Even a short, one or two sentence project synopsis is more useful than a condescending response like this.
