I agree. However, for the “what’s a computer?” crowd, manually adjusting the screen brightness is pretty advanced. They intentionally obfuscate settings they (a) don’t want people messing with - like the ability to show the entire right-click context or uninstalling Candy Crush and (b) which are likely to lead to screwing up their system - like entering their own namerserver IP address or opening ports in the firewall. Still, if I were in a room with Hitler and the person who decided to create the Settings app without all the control panel functions included, and had a gun with only had one bullet, Hitler would still be alive.
