Hyderabad, March 24 -- Once upon a time, humans had a curious habit - they used their brains. They solved problems, wrestled with ideas, made mistakes, corrected them and occasionally produced something called original thought. It was exhausting, inefficient and gloriously human.

Thankfully, we have moved on. First came the calculator, rescuing us from the burden of remembering multiplication tables. Then mobile phones saved us from memorising phone numbers - or directions - or, eventually, conversations. The abacus retired with dignity. Memory packed its bags quietly. Thinking began working part-time.

And now, artificial intelligence (AI) has arrived to complete the unfinished job.
