Thing is, everyone's value system is different. What is busy work for one person can be satisfying for someone else. So the bottom line is to do work which you derive value from. If you are working on a team of 100 people working on a feature which you believe is pointless, but it is still technically challenging and you are learning and you are having fun, then that's fine. It is paying the bills and you are getting something you value out of it.
e.g, there are people who think Metaverse is pointless. Does that mean all the engineers working on it are wasting time? Of course not, they are all getting something of value out of it - may be money, chance to innovate, chance to work with amazing people.
