Both are fairly uncontroversial: many humans not only benefit from jobs but in fact often depend on jobs for their livelihoods, and (2) should be self-evident.
This can change if the socioeconomic system is quickly enough and quite substantially restructured to make humans not depend on being compensated for work that is now being done by robots (not only financially but also psychologically—feeling fulfilled—socially, etc.), but I don’t see that happening.
