Looks great on my 25-year old CRT. I find it hilarious that we sharpened monitors so now we have to blur the rendering, because heaven forbid we see a pixel.

No, if we had infinite resolution monitors we wouldn't need anti-aliasing. You gotta bandlimit your signals or you'll see aliasing. That's just how signal processing works. Imagine if your audio player's output voltage jumped between 16bit levels instead of smoothly transitioning. It would sound horrible. That's how bad jaggies look to people who didn't grow up with slow computers

  Gosh just how did they manage with the CDs and 12-bit audio, like animals.

    With anti-aliasing filters, that's how.

    CDs are 16-bit. Digital audio players have had anti-aliasing filters for as long as digital audio existed because they'd sound horrible otherwise

    You know what I meant by "infinite resolution".

If you genuinely can't see the difference between 30/60/120 Hz, you should get an eye exam because that's not normal.

      > Fonts are typically infinite resolution because they are small programs that you execute. Vector fonts and vector graphics are two different things. Fonts define an outline. You can programmatically displace points on that outline but you are still limited in the types of outputs you can define due to this restriction and to the overall number of points per glyph the font system allows. They're pretty far from "infinite resolution" and the errors between screen space and font space are not particularly large and are probably not best understood through signal processing metaphors, was my point.
