I also don't know why anyone thought (or thinks, really) that Zoom was "a perfected technology" in any way, either then or now.
It went from zero to well over 60 at a pace almost unheard of, even in the tech world, and was pretty much beta software when this all began.
I also never presume anything that touches cyberspace is private. Period. End of Sentence. No matter how much any individual or entity insists they've come up with the magic complete privacy bullet in cyberspace, it has never, ever stayed that way.
