Alternatively, when I contemplate a world where I need to apply firmware upgrades to my light switches, worry about having to set firewall rules for my front door lock, and ponder what will happen if my letterbox vendor goes out of business and turns of their server - the sheer unadulterated, mechanical simplicity of taking a piece of shaped metal out of my pocket, flicking a light switch and then closing my front door by inserting said pice of metal into a small hole is just so very, very attractive. The lack of cognitive load is just magical
I'd say that's a very accurate description of an inevitable future, assuming we don't extinct ourselves or wipe our our technology progress by nearly extincting ourselves.
One way or the other, for example, automated cars are coming. We can say "but trolleycar problem!" Sure, we need to worry about that! But, no matter how hard we gripe about all the problems and scary things about the new tech, it is coming. It will happen, because there is profit to be had there and it is more efficient than having humans drive and a million other reasons that more than overcome the obstacles.
So, an IoT lightswitch may not be as inevitable as self-driving cars, but IoT valve meters sure as heck are, or IoT lightswitches for an oil rig, or IoT smoke detectors... in fact, some of these might become legally required, once they get robust enough! (similar arguments have been made that it may become illegal to drive a non-autonomous car without lots of training/licensing)
So, people like you and me, that prefer zippos and straight razors and automatic watches over quartz watches and fountain pens and manual-transmission cars, we'll still be able to have our mechanical switches, we just won't live in a world where everyone wants those things.
If you find manually managing those things easier than the occasional firmware update and making sure you buy things from companies that are reasonably reputable and have decent security practice, then by all means stick with regular options.
What if there were a world where your light switches are smart and don’t need firmware updates? The state of mass-market IoT right now is a bit of a shitshow, I’ll grant you, but that doesn’t mean it will always be the case.
People once groused about the complexity of fuel injection, too.
