It's a mass extinction event

Yeah me too, but I think it's not there yet, when you think out of a less programmer focused perspective, as most of the stuff in games is of artistic nature (which takes time to make, even with all the AI stuff) and otherwise simple game logic for most of these indie games. So something like an interactive GUI editor to "debug" is a must have for artists.

Sadly don't think Bevy's going to benefit too much from this drama. Most people from Unity will want a more complete toolset and probably won't be wanting to learn a whole new language. Can see a lot of indie devs making the switch over to Godot though
