The next macOS will be touch screen centric with elements getting bigger when you're close to touching them, rumors say. That being said, I run Tahoe and it works perfectly fine to me, I am not sure what issues people have with it. Sure, some corner radii aren't exactly the same but I honestly couldn't give less of a shit as long as it runs the programs I need.
I read a rumor about it being “touch friendly instead of touch 1st”.
Safari routinely using 20+ Gb of memory with a handful of tabs open. Safari tabs refusing to close. Unresponsive System Settings window. Random application freezes and crashes, Apple Music not playing music. This is on a 32Gb M1 Max. My M1 Air on Sequoia doesn't experience any of these issues, even if it has half the unified memory.
