Is AI Supposed To Help Us Or Replace Us?

Who asked for all these AI bots, apps, APIs, etc... to be developed in the first place? All I can see from my side are:

From my admittedly narrow perspective, the only field I see where AI can be of help, is in the medical field and maybe the socio-economic field. If it doesn't replace people's jobs and still improves the lives of everyone, then that is a good outcome.

But if it does the opposite. If it takes away jobs, while making corporations rich, then we need to ask ourselves: Is the net gain/benefits we get from using AI, a worthwhile trade over a world where services are rendered by real human beings? You know, people like you and me? I think not.
