I really want a way to get a generated voice recognition transcript for all that content people really think needs to be in video form. 2x playback is still 14:45 too long in this instance.

It's not that anyone thought it _needed_ to be in video form, it's just a conference talk. For reading there's the readme here: https://github.com/Polymer/lit-html and documentation site here: http://polymer.github.io/lit-html/

They both go into how lit-html works and how it doesn't just throw away and recreate the DOM on re-renders, though I admit the docs could still be better.
