How X Uses AI to Connect a Global Audience

TL;DR

X aims to connect people across languages, reward original creators, and help users gain recognition through public conversation. Its product team rebuilt the recommendation algorithm, expanded automatic translation, and developed systems for identifying original content, while pursuing a broader vision in which posts, articles, videos, software, and games can circulate globally.

One Foreig [music] So, Nikita Basan, welcome to our show. [music] Thanks for having me. I'm excited to be here. You're the head of product at X and you're char in charge of feed optimization, uh, creator features, and you're in charge of the spam counter measures. So, you're here in Tokyo, and you know, Japanese people love X. You know, I think two... Read More

Key Insights

• Japan is one of X's most deeply engaged markets, with Japanese users spending more time on the service than users in any other country, according to Bier. He connects that engagement to intellectual conversation, strong personal interests, distinctive humor, and an ability to spread messages effectively.
• X's recommendation algorithm is designed to identify the content most relevant to each person at a particular moment. It learns from how users interact with individual posts while supporting the platform's broader role as a real-time pulse of news, knowledge, and public conversation.
• Original-content attribution is central to X's creator payment strategy. After some accounts abused the revenue-sharing system by reposting others' work, X built technology to identify original authors, and Bier says many original creators subsequently saw their payouts increase.
• Automatic translation works by using X's AI computing capacity to process posts and present them to users in other languages. Bier says the feature revealed previously separated online cultures and sparked direct exchanges, including a discussion between Japanese and American users about barbecue techniques.
• X is intended to function as a meritocracy of ideas where a person's public contributions can change how others value them. Bier describes this as a form of social mobility because users can demonstrate their abilities, reach influential people, and create professional opportunities through conversation.
• Bier's path to X included publicly asking Elon Musk for a product leadership role after the company was acquired. The post did not produce an immediate job, but Bier later advised xAI, built relationships with people at X, and accepted the opportunity when it arose.
• Working with Elon Musk requires building toward the intended final form of a product, even when that route is difficult and could fail. Bier contrasts this approach with seeking shortcuts or quick wins and cites the complete reconstruction of X's aging recommendation system as an example.
• X's longer-term product vision extends beyond distributing text, articles, and video. The description says AI could enable people to create software or games, publish them directly into the timeline, and distribute those interactive creations through the same network used for public conversation.

Questions & Answers

Q: Why are Japanese users so active on X?

Japanese users are highly active on X because the platform fits behaviors that Bier associates with Japan: intellectual conversation, strong commitment to personal interests, distinctive humor, and skill at spreading messages. He says Japanese users spend more time on X than users in any other country and describes Japan as one of history's highest-penetration markets for a social network.

Q: How does X decide what content to recommend?

X's recommendation algorithm attempts to identify what is most relevant to an individual at a given moment. It relies partly on how that person engages with individual posts. Bier also frames the recommendation system within X's larger purpose: providing an authentic, current view of what humanity is discussing across news, knowledge, hobbies, and public conversation.

Q: How does X protect and reward original creators?

X built a system to determine the original author of a piece of content after detecting accounts that were abusing creator revenue sharing by reposting other people's work. Bier says the company acted quickly, that the identification system has worked effectively, and that many original creators have received higher payouts. X also doubled total creator payments during the previous year.

Q: Why did X introduce automatic translation?

X introduced automatic translation to move content across national, linguistic, and cultural boundaries. Bier says Elon Musk views X as a global consciousness, a vision that requires people to understand posts from other communities. X used its AI computing capacity to translate posts, allowing users who previously occupied separate language-based internet communities to communicate and exchange ideas directly.

Q: What happened when X translated Japanese posts for Americans?

Automatic translation exposed American users to Japanese accounts that had previously been difficult for them to understand. Bier recalls an exchange in which a Japanese account complimented Americans on their barbecue skills, followed by Japanese users sharing their own methods. One popular American account compared the broader experience to first contact because an unfamiliar world of skilled posters suddenly became accessible.

Q: How can X create social mobility for its users?

X can create social mobility by giving people a public place to demonstrate ideas, abilities, interests, and judgment regardless of their existing status. Bier describes the platform as a meritocracy of ideas where an identity that is undervalued offline can be reassessed through visible contributions. Users can also contact influential people directly, receive responses, and potentially create professional opportunities.

Q: What is it like to work with Elon Musk at X?

Bier describes working with Elon Musk as the hardest job he has ever held. He says Musk focuses on the intended final state of a product and pushes teams to build toward it, even when the work is difficult, filled with obstacles, or at risk of failure. Rebuilding X's recommendation algorithm from scratch over a difficult two-month period exemplified that approach.

Q: What could X become over the next five years?

X's stated direction extends beyond making text posts available worldwide. Bier wants translated articles and videos to become accessible to anyone regardless of location or language. The description also predicts that AI could let users create software and games, post those creations directly to the timeline, and distribute interactive work through X alongside ordinary public conversation.

Summary & Key Takeaways

• Nikita Bier describes X as a real-time view of human conversation, news, and knowledge rather than merely a source of passive entertainment. He argues that its users are intelligent, influential, and deeply invested in their interests, with Japanese users standing out for unusually high engagement, humor, and skill at spreading messages.

• X is using AI translation to let posts cross linguistic and cultural boundaries. An exchange about American and Japanese barbecue illustrated how translated conversations can create spontaneous cultural interaction. Bier says the longer-term goal is to make text posts, articles, and videos accessible to people anywhere, regardless of their language.

• Bier calls working with Elon Musk the hardest job he has held because Musk pushes teams toward a product's intended final state instead of relying on shortcuts. That approach led X to rebuild its recommendation algorithm from scratch, strengthen original-content attribution, address spam, and envision timelines capable of distributing software and games.
