A durable advantage means maintaining a lead by advancing again before competitors can catch up, not that competitors never learn the same things.

“By durable advantage,”

“I don't mean”

“mean um they never figure out what you already figured out i mean that by the time they catch up you've already moved ahead so”

“that you it's like you know you keep running as fast as they're running so that even though they're only six months behind they can never quite catch up because by the time they do you're six months ahead again”
