That’s absurd. You don’t need to understand the inner workings of the kernel to know what a root account is. If you’re regularly encouraging people to install a new OS when you aren’t even confident in their ability to understand what a root account is, you’re not doing them any favors.
No one talks about land usage for solar either. Which is a real shame, because with some relatively minor redesigns solar plants can be integrated into the ecosystem without causing massive damage, instead of what usually happens which is just clear-cutting a huge field and destroying any plant and animal life there.
