How do economists think about work some people do for pay while others do for free?

Thinking about examples such as childcare, housework, cooking, or even having a friend DJ at a party. Anecdotally it feels like companies like Fiverr, Uber Eats, etc. are slowly replacing what people used to do for free for themselves or as a favor to friends/family. Does this mean the trajectory of society is that in the future more and more work will have capital assigned to it? Is that a good or bad thing & why?
