Indeed, and it's hard to decide which of the two is the silliest.
Which returns us to the last time I visited:
There’s no discount rate to “find out.” In part because like climate sensitivity we only can establish a very rough ballpark, and in part because, like interest rates, it’s a human decision.
It'd be hard to deny that all we have are ranges of values in both cases. Yet the luckwarm playbook comes with this very pussyfooting in both cases.
