Do 10x engineers get 10x the wages? Somehow I feel being exceptionally better than other engineers is just unfair to both of you and the ones worse than you. I wouldn't want to be a 10x either, I'd rather just be normal engineer.
3x bonus multiplies (Redefines Expectations) are extremely uncommon. Level increases certainly help but like, L7 only makes ~3x what L5 does -- not 10x. And there are few L7s and very few L8+.
