I was once the Product Manager for logged out Twitter. I still can't believe what they did here. Logged-out is a huge reason for Twitter's cultural relevance. This "concentric circles" chart from 2014 shows its importance.

SORA vs Pika vs RunwayML vs Stable Video. I tried the same prompt as in one of @OpenAI 's examples on the other GenAI video models. All of them produce much shorter videos around 5 seconds. IMHO SORA's doing prompt enrichment just like Dall-E, will try that next.

How many is enough? Slack takes 3 people to deliver value. Zoom needs 2. AirBnb needs 100 reviewed listings in a market. Uber needs to get ETA under ~5 minutes to reach that point. Networks that are harder to get starter are more defensible the product is in the long run.
