Yeah I don't understand why he is shocked that this communicates wirelessly. He even bought a modern flat with Ethernet because he clearly knows how much pain it is to add wiring to a house. Very weird.
It's painful to add wiring to a house as a random normie user. It's not painful if you're an installer or a construction person.
Or at least this is my understanding why all construction is still done in a way that makes it near-impossible for the user/dweller to change anything without having to do general renovation of half the place. Which, again, is hard primarily because it makes no sense to buy all the hardware that makes such work easy for a single job.
