If you wanted to show you're rational, you can replace any words with their 5 years before technology: subpixel hinting (anti-aliasing) for fonts, 3D, Compiz, working 3D video drivers, who cares? Qt... who cares? A toolkit on top of X? Who cares? XTerm is a living proof that we could survive without any fancy graphics. X- we can draw directly using a framebuffer, who cares? Classes to separate real and big codebases? We can simulate in C, who cares about C++? Xml, who cares? Ini files and binary ones are both faster, so who cares about validating Xmls?
And so on, are too many areas that we take them today for granted and I think we should be really respectful for anything that is given more or less for free (as in beer at least) as a lot of these things are made with a lot of hard work. I'm sure that you are using a browser so advanced that it can likely make some parts of the program to run close to C performance because they have a Just-In-Time compiler, and you just read a text using sub-pixel hinting and if you can read this forum and you're not using a lynx browser, you can see it with CSS (why someone whould need a themed site, so who care about theming capabilities!?).
Note: don't troll, is not fun, is not smart
