Was Zuck Right about Chinese AI Models?
Near the end of Mark Zuckerberg’s almost-three-hour interview with Joe Rogan, he gave a shoutout to DeepSeek. He called its new model, which has taken the AI world by storm, both “very advanced” and as another example of why Chinese AI models cannot be trusted, because it is censored and undemocratic. If you ask DeepSeek’s model for its opinion about Xi Jinping, “it will not give you anything.” If you ask whether Tiananmen Square happened, “it will deny it.” These are Zuck’s words, not mine.

Software Is Not Dead
When I started working in the enterprise software industry almost a decade ago, the most effective (and thus fashionable) go-to-market (GTM) strategy was bottoms-up “land and expand.” Some of the poster children back then of executing this model to extraordinary success were Slack and MongoDB.
