Another issue is that modern personal computers make it massively easy to hide what it is doing.
The phone before me seems to be idle as best i can tell, but if i fire up a process viewer i see 20+ ongoing tasks.
This in contrast mechanical devices of old that only did the one task they were built to do, and were very "loud" (not just auditory) about when they were doing it.
Heck, recently i found myself wondering about hooking up some kind of audio system to wireshark and play around with having various packet traffic produce various sounds. This after reading about a guy that set up his phone to play certain noises to his hearing aid based on the characteristics of wifi networks encountered when walking around town.
Consider also that we suspect something is up with a car or similar because the steering wheel develops an odd rattle, or some unfamiliar noise is heard when doing certain things.
Never mind the old analog modem handshake where we could tell by experience when we got a bad connection, compared to the modern variant where we have to check some "dashboard" to tell if we are connected at all.
