What advantages does Linux have for children over macOS? It’s UNIX, with the shell and all the OSS packages you could want. Very few children need to recompile the graphics stack, kernel, or drivers.
Very few Linux users too.
The advantage is not locking them into a corporate environment that's getting more and more questionable and give them the oportunity to actually learn about computers.
I don’t get the impression that most people care to learn about computers, they just want things to work. In this way I’m not sure it’s much different than most other things we use in life.
You can use Wine to play a lot of games on Linux. Good luck doing that on macOS due to their refusal to support Vulkan and 32-bit. macOS doesn't offer any benefits in comparison with Linux, only disadvantages.
What is the advantage to the average person to be able to run 32 bit apps?
Most game engines are supporting the metal api, or use vulkanVK as an abstraction layer.
Have you considered implementing an office full of linux desktops? With a team of designers? Product Engineers? Salespeople on the road constantly? I'd imagine if macOS has no benefits at all, IT managers everywhere would be switching to linux desktops. Why do you think this hasn't happened? especially since linux has no disadvantage compared to macOS?
