...the country should stop focusing on the success of the M-Pesa mobile money platform. “I don’t see any unique ideas. I have not seen something that can genuinely be the next big thing. I am just not convinced. M-Pesa was invented five years ago, but everywhere you go, every other technology conference, the only thing we talk about is M-Pesa. We must come up with something new.”
