Everybody privately shit-talks everybody. The phone always listens to it and records it. A viral hack that turns all this shit-talking into texts. Everybody in the world suddenly gets a thousand shit-talking texts from their family, friends and associates. Society dissolves.
Your criticisms are very weak. Sorry.
Instead of looking for ways to defeat me you should just go with it. For example you could consider what the societal upheaval would look like. How would we recover. What growth would it inspire etc.
I mean, really. What difference to my point would 99% shit-talkers vs 100% make?
