It's an app that matches drivers with riders or deliveries. There's not much to 'mature', so I doubt that they will grow much in profitability.

I can absolutely see this happening for transit companies like Waymo that are still in the maturation process of developing novel infrastructure.

Mature in a sense that Uber has invested billions in operations to get deals with cities & airports, developer legal expertise globally, and has technology that allows them to operate globally.

Saying Uber is "just an app" isn't a strong argument. It overlooks the marketplace dynamics that in themselves are a huge moat. You can also say "Instagram" is just an app.. But good luck trying to recreate that level of success.
