谷歌人才流失，但仍拥有庞大数据和算力优势

a significant brain drain at google deepmind, marked by demis hassabis moving to chairman and jeff dean departing, has fueled speculation about the company's decline against openai and anthropic. despite this, analyst gary marcus argues google remains a formidable force due to unmatched access to user data, custom tpu hardware, and a $132 billion profit war chest. the company can survive a fragmented llm market because its core business relies on search and youtube, whereas competitors rely solely on ai revenue. ultimately, google may outlast venture-backed startups even if it fails to dominate the foundation model market.
