TREE NEWS update: DeepSeek machine learning engineer Liu Shengyu published a viral essay on September 14 after delivering the main attention operator for DeepSeek V4.1. Liu, a Peking University Turing Class member who joined DeepSeek in April 2025, wrote that AI will match or surpass his hand-written operator work within six months to a year, forcing him to retrain as an AI agent operator rather than face unemployment. The essay topped Zhihu’s trending list.
DeepSeek Engineer’s Essay on AI Replacing His Craft Tops Zhihu
This is less about one engineer's career move than about the internal culture of a leading AI lab: the person who delivered a core operator is publicly betting his own role gets automated within a year. That candour, and the Zhihu reception it drew, matters because it signals how fast frontier labs expect their own tooling to shift, and it frames the retraining question from the inside rather than as outside commentary. Whether that self-displacement timeline holds, and whether agent-operator roles absorb the work as described, is the open question.
