What makes this approach "modern"? What is this approach the alternative to?

As someone broadly unfamiliar with text rendering it's not clear to me. An introduction to these points would be very helpful

It's part 1, so I would hope the author plans to move on from the basics here into more modern techniques (things like subpixel anti-aliasing, ligatures, etc).

Absolutely, Subpixel AA, Kerning, Ligatures, Gamma Blending, and Emojis will be treated
