I'm good at only one thing, and it's not valuable

If we call "a human with AI" what it in fact is - a "meat proxy", then yes, they will absolutely survive because customers prefer talking to a human. This human isn't anyone with agency or decisionmaking power anymore, not an important stakeholder a SWE of 5 years ago used to be. They are like a domestic servant, mainly existing to boost the ego of their master and to make interactions with the system closer to what they are used to.
