I'd put it a bit differently than the OP - for me interesting and meaningful work means that it's actually benefiting society in some way. That would mean that even the 'boring' aspects would have some kind of meaning ("we're trying to cure X" or "We're working to help solve global warming"). Too much work now is just trying to sell stuff to other people, get people to click links, get people riled up so that they're engaged with some social media platform - it's not helping us as a species.
