Why do we still use stepper motors? (sopuli.xyz)

Why are 3D printers still stuck on stepper motors? Why haven't we transitioned to servo motors with encoder feedback for positioning?

Is it just too cost prohibitive for the consumer-level? We would be able to print a lot faster and more accurately if we had position feedback on the axes. Instead we just rely blindly on the stepper not skipping any steps when we tell it to move, hoping for the best.

Yeah the big issues with servos would be that even with very good controllers you'd end up having to constantly bump to the corner 0s just to ensure you got the right location. Stepper motors can be relied upon to hold the position.
