My broadband access has been wireless ethernet, over a roughly 5 mile hop from the nearest tower, for roughly 20 years. I'd still be using 14.4kpbs modems over copper telephone wire without it. From the post in the South pasture where we pick that up, it's wired to the two dwellings on the place, and pure wireless after that, including extension APs in two more outbuildings, and a LR outdoor AP. Rarely have any trouble with any of it. Of course, I don't have to worry about my neighbor's router causing interference - the nearest neighbor with broadband is half a mile away, most of which, from a line of site point of view, is through dirt. Before I retired, I was CTO for a hospital where we ran 14,000+ APs on roughly 100 sites, serving 100,000 or so employees, patients and visitors daily. I regularly used it at a restaurant across the street from one of our buildings. The service was highly reliable and available nearly everywhere. (And, believe me, if you took away a surgeon's wifi that she or he used to do quick email and other updates between surgeries, you'd know it in short order.

So, yeah, wifi can require some management, but the thought of running all those laptops, phones (you couldn't rely on cell service - which of course is another form of wireless - inside most of the buildings - worked some places, not others), and portable medical devices only on wired ethernet is a non starter.

As for other forms of wireless - Bluetooth and BLE have their issues, but you get an awful lot in return.
