I can see this happening but (imo) that is ahead of the other stuff that comes to fruition first. The company is in ‘telecom’ or networking etc. While they won’t be building the smart cities they sure can be part of the networking, backbone of them. (Payments, education et ). Thing is there isn’t a standard so would be a challenge to develop the app to address all different types and or features of smart cities. But maybe so in the future ;)
