Look folks, in order to win this metric game you need to be doing something where you are answerable to as few superiors as possible. It didn't used to be this way where minutia was tracked and analyzed. Now all of the leadership running businesses want to balance everything on the point of a pin.
Don't they understand how unstable a system managed like that is?
One slight perturbation in the metrics, can cause great instability in such a system. Think of it as the "butterfly effect" in chaos theory. One slight perturbation, and you suddenly have an category 5 hurricane on your hands.
So getting back to being answerable to as few people as possible. This is going to become more and more of a requirement in the future. The more people you have to answer to, the more constrained your life is going to be.
When you have metric systems in place like the one that is/was at Duolingo, your life is going to end up revolving around keeping yourself high enough on the metric board to ensure that you won't end up in the unemployment line.
If you have debts to pay such as mortgages, car payments, and student loans you're answerable to these loan servicers as well. Student loans are usually not dischargeable in bankruptcy, and you still need to pay for rent, groceries and medical care to remain the bottom level of Maslow's hierarchy of needs triangle.
So if you can't stay on the employee leaderboard in the CEO's office, then you'll end up on the streets, and everyone you are answerable to for the basic needs will be saying: "Pay up sucker".
Doesn't seem to me to be a great way to exist.
