My thought is that its all buzz words. its not gonna take over. MQTT itself is a nice concept but with bandwidth being cheaper and more readily available than it has ever been, it kind of makes it not worth investing in that infrastructure. Then no end devices support it which means you have are moving the traditional polling model of having the server do the polling to a cumbersome box called an edge of network gateway that basically moves the great tools most scada softwares have to create tags to this edge of network gateway.
I just dont see it being feasible long term. Not to mention that depending on your design, you may go from having updates every 5 minutes to updates every few seconds. Is 100 times more data in your database going to be useful? Maybe in some cases... but I think collecting a crapload of data just to do it is a waste of time, money, and space.
what it boils down to is after we are all dead and gone 70%+ of devices will still be using analog signals or one of the 10 flavors of modbus over a serial port.
