Maybe I'll have to eat my words in a few weeks but I can't say I'm super concerned. M1 seems a lot like the A14, which is a lot like the A13, which is a lot like the A12, etc...

I'm more concerned about how long it will take for most apps to have full support for both macOS Catalina and Apple Silicon. When the 2012 retina MacBooks came out, quite a few apps were awkwardly pixelated for a long, long time.
