Complexity Has to Live Somewhere
We try to get rid of the complexity, control it, and seek simplicity. I think framing things that way is misguided. Complexity has to live somewhere. Embrace it

Which is better on Android: divide by 2 or shift by 1?
I've been porting the AndroidX collection library to Kotlin multiplatform to experiment with binary compatibility, performance, tooling, and the different memory models.
