who are these adult humans who can’t face choices? I don’t really understand how or why they even chose their PC in the first place.
It sounds like such people will be a lot better off with android or mac, or windows or chromebook. If they want to do games get a console.
It’s sort of like if a person has no enthusiasm for or interest in cars, they might be better off with a rental.
if you really want to make another version of something like chromeos for this audience, there is nothing stopping you. But the free/foss open source world is always going to have choices that bamboozle these people who can’t look at the mint website and pick one, or just resolve to test all three.
