I cannot see any IoT revolution. Let's globally forget about the consumer market, already dead, but focus on the industrial applications. Going from $10 to $1 a sensor didn't trigger any change. Not surprising when yearly maintenance/battery replacement/shipping/installation/network fee is circa $50/y per sensor and this economics didn't change. Big data didn't change anything, as the cost of storing info was already peanuts before.
