If we ever see a world where robots need to be useful outside of a factory with perfectly flat concrete floors, then yes - there needs to be continued evolution in traversal over uneven ground and around unanticipated objects. Bipedal locomotion is useful for this (although not the only solution).
Right now the hardest jobs to replace will be those of plumbers, electricians, carpenters, etc where they need to operate with fine motor skills in unique and challenging locations - no two ever being the same.
i think search and rescue is a great application of humanoid robotics, you need something very versatile and a human body is not a bad model for a universal terrain form factor.
