Internet of Things
This is very much not a hype and is very widely used. It’s not just smart bulbs and toasters. It’s burglar/fire alarms, HVAC monitoring, commercial building automation, access control, traffic infrastructure (cameras, signal lights), ATMs, emergency alerting (like how a 911 center dispatches a fire station, there are systems that can be connected to a jurisdiction’s network as a secondary path to traditional radio tones) and anything else not a computer or cell phone connected to the Internet. Now even some cars are part of the IoT realm. You are completely surrounded by IoT without even realizing it.
You like tech? You like wiring up and programming state-of-the-art commercial automation, access control, and cctv systems? You like to move around as well and work with your hands and tools, all on the same job? Become an electronic security technician. Been doing it for 20 years, it’s great, and always hiring, almost never firing, unless you get caught smoking meth or something.
Nothing wrong with a more blue-collar style job.
