## AI 摘要

推文以排比句式讽刺了AI行业中部分人热衷于在社交媒体发布浅薄观点（如转发推文、发布提示词技巧），却缺乏扎实技术功底的现象。作者强调，当他人追逐热点时，自己专注于钻研底层技术与解决实际工程问题，例如深入研究芯片架构图、掌握JAX等工具原理、调试计算集群与硬件故障。当新产品（如Rubin）发布，面临推理成本建模、机架级供电及NVLink带宽限制等复杂实际问题时，这些缺乏深度实践的“空谈者”反而需要向具备真才实学的实干者求助。

## 正文

While you were posting hot takes on Twitter， I studied the die shot.

While you were chasing clout with your "AI will change everything" & "Top 10 GPT-3 Prompt tips" LinkedIn posts， I mastered the JAX first principles bible coauthored by my cousin.

While you wasted your days reposting Sam Altman tweets in pursuit of engagement， I cultivated deep knowledge of MoE routing， KV cache sizing， and FP4 GEMM throughput on tcgen05 MMA uarch becnhmarking

While you were partying at NeurIPS afterparties， I was SSH'd into a Slurm cluster at 3am debugging enroot squashfs errors & driving to the colocation to replace broken SXM modules.

And now that Rubin is launching and your clients are asking about inference cost modelling and rack-level power delivery and modelling interactivity which are NVLink bandwidth bound， you have the audacity to come to me for help
