I still miss the advantages for these cases.

Zero-maintenance and upgrades.

Update it every once in a while or setup auto updates. I do not see any difference between traditional os and immutable. You’re likely not modifying any system files anyway.

You’re overthinking it, there’s no reason to care if the root disk is readable or not. If it updates reliably out of the box there’s no reason to touch it.

Are they really going to brick their system? That would require opening the terminal. But I mean, fair.

You don’t need to open a terminal to brick a traditional linux system they tend to do that on their own.

What I do not understand is why there are users swearing by bazzite and other immutable distributions. These examples you make is basically for users who just do the most basic operations with their systems.

I can’t speak for “immutable distributions” but for bazzite it’s to ensure working upgrades.

What I do not understand is why technically adept people are so excited for these kinds of distributions?

I’m technically adept at Linux I expect software to work. (system upgrades should work, app installation shouldn’t break the PC, etc.)
