IoT is pretty great for manufacturing (talking billion dollar manufacturing). I don't like seeing my precious IoT lumped in with NFTs.
Not that we aren't still quite far away making it all fully working and secure...
What will IoT will bring to manufacturing that hasn't already existed for the past few decades? I started my career in manufacturing at a pretty large company around 2010, and quite literally every process was being monitored over a network. I worked with a framework called XMII (formerly Lighthammer[1]) that integrated with SAP and allowed us to read from various sensors collecting data on manufacturing lines and built dashboards for monitoring.
