"It reminds me of the many James Bond movies we would have seen over the time, where the devil really is a master of technology," he said.
Kotak hinted that the onslaught of digital disruptions is also challenging the way banking is done.
"As a banker, when I sleep at night, I worry about whether I'll have a bank next morning, will there be an Ali Bank or a Flipkart bank or some other bank doing business what we do," he quipped.
"In telecom, SMS is dead and there is Whatsapp. But I can't figure out what is the business model of WhatsApp," he said, adding that companies like it and others like Facebook and Twitter are first creating the user base to make money later.
"This long tail model has a phenomenal theory which has three parts --- keep on getting user, get them to use more and only after that think about making money. That is the Facebook, Twitter, WhatsApp model," he said, acknowledging that it's difficult for traditional businesses to comprehend this.
Kotak also expressed concerns about job creation in a digital world which is driven by technology disruptions.
