This what generally people think of 10x. The imaginative 10x heart surgeon would do following:(any or all of it)
1. Take 10 times less time performing heart surgery.
2. Could perform successful surgery at 10 times less cost.
3. Invent new ways of doing work of 10 heart surgeons.
4. Survival rate of his/her patients would be 10 times that of other heart surgeons.
5. Could perform heart surgery so complicated that it would generally require 10 heart surgeons during the surgery.
Are you going to find such a heart surgeon ? If so, how many? would entire healthcare system be functional if all hospitals are adamant on just hiring 10x surgeon and at the same time advocating bringing more 1x heart surgeons into the market.
