Some people love to use the expression “before it was cool”. In hindsight, it can be applied to almost anything that gains acclaim. According to this Reddit thread, for example, Facebook was already cool when it was still known simply as “The Facebook” way back in 2004. My point: the “before it was cool” expression is really about when something’s value or significance is recognized very early on, and this can certainly be applied to many of the technological advancements we see today. Connecting devices, or instrumenting machinery with some form of connectivity, to capture data and provide control, was a used in many industries, before the term ‘Internet of Things’ or ‘IoT’ became cool and all pervasive.
