I don't have any trouble understanding people when they say something like "I'm in the sort of sustainability space around kind of bringing synergistic value-add to other people's work around this kind of space." They're simply saying nothing. I remember watching some cartoon where some aliens are watching humans converse and they interrupt by saying "ritual gum flapping time is over". That's all this is: ritual gum flapping. When two people flap their gums at each other for a few minutes, it increases their comfort with each other and that social comfort helps keep society glued together. Sometimes conversations are about exchanging ideas, other times they are purely about socialization. In this case, the conversations aren't about the ideas, they're about having a conversation.

It may seem pointless, but a lot of being human is pointless.
