I think it's safe to assume that 80+ wireless devices puts you in the top few percentiles. So while not unheard of, not "normal" exactly. And even less common in dense apartment environments where having more than 3-4 rooms is unusual.
I've heard of at least a handful of people that have done this and more this year alone.
A few phones, a computer or two, TV, a few wifi speakers and a miscellaneous light or temperature monitor. It’s not hard to exceed 10.
Having said that, if I had the money, I'd totally automate everything in my house as well. It's just too much fun not to.
Some of IoT device you list I’d actively avoid, but thinks like robot vacuums is really useful.
a) Fire detectors. 13 units including the central. (Basically one in every room where something may conceivably catch fire.)
b) Leakage sensors in any room with faucets or washers in it - 7 units.
c) Kitchen appliances - 5 (Cook top, two ovens, fridge, freezer)
d) HVAC - 7 units (Central ventilation. Heat pump. A handful of electrical panel heaters.)
It quickly adds up - at least if you live in the boonies where land is effectively free.
I.. ahh, don't think so.
I graduated from Software Engineering in 2003, and recently worked for Canada's biggest Telco for 4 years. I didn't even know half of the IoT's on your list even existed !

There is a wireless LAN in my space, all devices that need connectivity should just use that LAN.
More hubs are more headaches. You need to not lose their power adapters when moving, you need to find a place to put them that is within range of all your devices (may not be as easy as Wi-Fi since they may be using other bands that don't transmit as well or have FCC restrictions, and I already have Wi-Fi mesh network everywhere, you can't easily mesh arbitrary protocols on arbitrary frequencies), you need to set them up using typically a shitty spyware phone app, you need to keep their firmware updated in addition to device firmware. And you also need a hub for every brand of appliance you buy. A Philips Hue hub will not work with some other brand of lights. Whereas you can mix and match hub-less lights and you don't need to have a pile of hubs on a shelf somewhere.
It's definitely not normal.
I don't feel the need to have a single "smart" light bulb or outlet. If I'm turning a light on or off, it's because I'm leaving or entering the room, in which case I'm walking by the light switch anyways.
