WHO am I? is a deep philosophical question, one which can take a lifetime of pondering. Humans are prone to ask such profound questions; so, after 7.5 million years of computing by the Deep Thought super computer, we have the response: “The ultimate answer to life, the universe and everything is: 42.” (Intrigued? Read The Hitchhiker’s Guide to the Galaxy by hilarious sci-fi writer Douglas Adams.) At a more mundane level, today I can answer the identity question, like Deep Thought, in numerals: “xxx6910” — that being my partially-redacted Aadhaar number. This gives me (and some 1.1+ billion Indians) a digital identity, which can be accessed anywhere and anytime. More important, being biometric and retina-scan based, it is unique; therefore, better than a conventional name which can — and often is — duplicated (think of how many Anil Kapoors or Srinivasans you know, leave alone Buntys and Pinkys).
