“I think that language is overrated; some people even claim that you cannot think without language.
If you look at the political debates we pay an enormous amounts of attention to non-verbal communication. In fact, around 75% of our decisions are based on that.
And so I would want a day when we go without symbolic language.
On such a day, we may still sigh and scream and laugh, and do all kinds of other non-verbal things we need to express ourselves without language.
Without language we can still tell people that we like them or hate them or they are our rivals, for instance.
I think this would reduce the amount of backstabbing and nastiness that goes on because if you want to express a rivalry you would have to do that to their face.”
