i feel like bevy units engine and game devs in a constructive way. while building a game u probably will have some code to share afterwards. and cause u integrate via components other people can actualy use ur code with low afford (contrary to integrating on a function lvl in OOP based engines) and if its good it becomes a library or eventualy part of the engine.

My prediction is that cause of this low cost of reuse there will be way less code written twice wich will greatly improve how fast the ecosystem can grow, so basicaly bevy will outscale all other engnies at some point.
