The underlying issue is the technical failures of video calling, not the social environment it's used in.
Would you mind explain me why there isn't anything (or only little) done in that area? I guess we could implement some assistive checks for input and output audio streams? What is blocking us to implement a "handshake" that will verify that all is fine? - let's say communicators will send a recorded sample "Hello World" message over wire and check the microphone, volume, noise etc. In my opinion the pattern how we resolve the "I can't hear you" problem is a repeatable checklist that we more or less confidently do, so why we can't implement it as some algorithm that takes care of those problems in automatic way?
Whenever I’m in this mode (which basically means whenever I’m on a conference call) I wonder what percentage of the GDP this represents, in aggregate.
And there are even more problems with consumer telepresence:

But i feel that they too are solvable, if you care enough(like when you want to keep in touch with you senior parents).
I spent the past 5+ years in jobs where I had to have multiple video calls per week. I used every tech imaginable, from those that cost five figures to the gratis ones. If these problems are solved, why is the experience universally terrible on all of them?
When I call my parents, it's over the plain old phone line, because I actually want to talk to them. Not seeing their faces on the screen is a small price to pay for not having each and every call turn into an impromptu debugging session.
I also find that Apple's FaceTime is the most consistently good and functional with little "can you hear me now".
Have you tried putting that both on your and your parents' locations ?
And what kind of internet you two are using ? and are the devices using wifi , or are wired ?
This issue is pretty far down the list IMHO. Above it are fixing the obligatory 5 minutes of "Can you hear me? I can't hear you" before the actual conversation starts.
Face-to-face conversations also lack "Please mute your mic when you're not talking because the background noise is annoying". "Did you forget you're muted?". "Can you repeat that, I can't understand you". "The video/sound is cutting out". "Where's this echo coming from?". "Please say something on your end". "What's that noise?". "Please use a headset next time". "Sorry, the call dropped out". "Let me call you again, maybe this will fix the issue". etc. etc.
Video chat is one of the great unsolved problems of computing. Yes, camera location is there as well - especially on Dell laptops that for some reason have it looking up from below into your chin. But that is really one of the lesser issues as far as my experience goes.
