If total global data consumption in 2025 is about 175 zettabytes, as IDC expects, then IoT devices in use at that time (perhaps 42 billion IoT devices, according to IDC) might represent 79 ZB, or perhaps 45 percent of total global data generation.
Of course, others expect far fewer IoT devices in 2025, with some estimates at about 22 billion, not 42 billion. But even using a lower 22 billion IoT device estimate, such devices will significantly outnumber smartphones and other human-used connected devices.
The point is that IoT devices will drive a significant portion of global data traffic and processing loads by 2025 or so.
