Agree. productivity as in "works faster" is not something that justifies being treated (and payed) as 10x engineer. Evaluating "value" of an engineer is also a topic of itself. At the end of the day, this is a team sport. even when a certain project is super successful (and in some cases it might take few month to see business impact) it's not always easy to know how much each individual in the team contributed to this success. BTW - same is true for failure.
