There's going to be more and more use cases, but only in select geographical areas. There's no real reason to pick Starlink over e.g. 5G, when 5G is cheaper and cover 99% of your locations. You can then pick Starlink, microwave, or 2G (if you don't need a lot of data) for those special cases where 5G doesn't have coverage.
Then you have the truly remote areas where you have no choice, it's Starlink or OneWeb, but that's still a niche.
