I think a point to consider is that for jobs for "tasks only humans can do", the precise job/opportunity for employment may not exist, but I agree that some opportunity will be created that utilizes that human skill that hasn't been displaced yet. This lag between human-replaced and human-finds-job could be problematic to the structure of society (also, consider the current human-job-search). A UBI here could be a shim (also, government welfare/unemployment support) to help support society during the lag - a buffer against the unknown which can help with the necessities (imagine having to find a job and deal with the prospect or being homeless because your were replaced and couldn't pay rent, that will exacerbate the problem.)
