    You can e-mail sacha@sachachua.com to call dibs on editing the captions for one of these talks. This year, we're experimenting with using OpenAI Whisper to provide auto-generated VTT that you can use as a starting point. If you're writing them from scratch, you can choose to include timing information, or we can probably figure them out afterwards with a forced alignment tool. Also, if you feel like making chapter markers, that's cool too. More info: Editing captions, captioning tips
