Is it conceivable that one of our greatest inventions, the phone number, is about to face extinction? Just ask Mark Zuckerberg. Earlier this year, when asked if Facebook would be around in 100 years, as long as Ma Bell has been around, Zuckerberg responded, “I don’t know. But I don’t know how long telephones will be around for.” Will they be around for ten more years? I’ll go even further. It may not even take 5 years for the phone service, as we know it, to meet its demise.
