DeepSeek engineers also have AI anxiety: It won't lead to unemployment, but a career shift is necessary.

Under the torrent of AI, even DeepSeek's top engineers worry about their future careers. Liu Shengyu, a machine learning systems engineer at DeepSeek, published a long article titled "I Had to Bury My Talent in Yesterday," in which he mentioned that in the face of AI's rapid progress in capabilities, he would not necessarily "lose his job" in the future, but he might have to "change professions." This anxiety comes from an engineer standing at the forefront of the AI wave. According to his resume, Liu Shengyu has been working on machine learning systems and operator design and optimization at DeepSeek since April 2025. Before that, he was a student in Peking University's 2021 Turing Class, served as captain of Peking University's supercomputing team, and led the team to a top-two finish in a world-class university supercomputing competition. A few days ago, DeepSeek released the new v4.1 model, pushing its capabilities up another notch. Liu Shengyu mentioned that the main Attention operator of DeepSeek v4.1 was written by him, and he is proud of DeepSeek v4.1's success. But what he is very clear about is that in another six months or a year, the operators written by AI will most likely be just as good as those he writes, or even surpass him.
