Machines are taking over. OK, not like they did in "The Matrix," but machine-to-machine (M2M) technology, aka Internet of Things, is making serious inroads. In sectors like healthcare; security; automotive and transport; and financial services, the ability of machines to communicate internally and with the outside world is changing the business landscape. The numbers vary depending on who you ask, but predictions about the general direction of the IoT market does not—the arrow is pointing up. According to research firm Analysis Mason, IoT will produce $88 billion in revenue by 2023, up from $10 billion in 2013.
