I am so sick of seeing this ridiculous diagram being labeled the “Dunning-Kruger effect”. Go read the actual 1999 paper they wrote. The key takeaway is that the lowest quartile of people tend to overestimate their own performance, and the top quartile underestimate theirs. It doesn’t posit anything like this graph, and this is just an ironic example of ignorance.

And second, I am so sick of seeing these ridiculous distro comparisons. Stop with this elitism, even if done humorously. People of all experience levels can be found using different distros, and they all have unique advantages, disadvantages, and communities built around them. Don’t shame the great effort that people put into maintaining and developing distros, repositories, and packages. A noob can use Arch, and a master can use Ubuntu. Use what appeals to you, and be happy in knowing you can experiment or stick to anything. This is the beauty of FOSS and the Linux ecosystem; it’s a great place for both tinkerers as well as those who want familiarity. There is no one true way.
