Maybe they can't do all jobs, but it can be still a problem if they take other jobs. E.g. if self driving cars can be perfected then you'll need much less cab drivers and truckers. Or if they invent cleaning robots which can clean malls and shops then lots of cleaners will be out of job. So the robots won't have to take all the simple jobs, because if they take a lot of them then those changes will still cause serious social problems.
