It's interesting to see an argument against ClearType/font smoothing, but not anti-aliasing in general. They both change the font from what the designer intended, so why is font smoothing so much worse? I actually disable anti-aliasing in games on my 4K display - not just for performance, but because anti-aliasing genuinely isn't needed at that density. I think the author could go all the way here too, since after all, AA is just another crutch for low-density displays.
