I like Apple's push to make apps 64 bits. It has been slow until recently, but, the last month, a large number of apps have been re-released as 64-bit apps. Then, there are holdouts-- apps that could have been fixed a long time ago and haven't been. I've been using System Activity Monitor (arm64 itself) to see which apps are actually running as arm64.

Feel free to check and add your own. Too bad Apple doesn't display the 64-bit capability in the apps section of iTunes.
