New Delhi, Fears that artificial intelligence could render humans redundant are misplaced, with the real breakthrough lying in combining human judgement with machine-scale automation, Jeetu Patel, President and Chief Product Officer of Cisco, said. "I don't see a scenario where humans are completely extinct of contribution of value to society. But I think humans are going to yearn for human contact. "I think human judgement and instinct are going to be pretty important to make sure that you can have exercise. "On costs, Patel said AI remains expensive to train and run, but unit economics are improving rapidly.
