Model Collapse Isn't New, nor Is It Specific to AI, Argues Dev Blogger

A blog post pushes back on the narrative that model collapse is a unique AI-era crisis, arguing the phenomenon has long historical and technological precedents.
Key points:
- Model collapse—degradation from training on repeatedly copied or synthetic data—is often framed as a novel risk of the synthetic-data era.
- The author draws parallels to older systems: information distortion through retelling, generational photocopy degradation—any "copy of a copy" loses original information.
- The crucial difference is that fresh, real source data can break the loop, and AI training pipelines can do the same.
The takeaway: collapse is a manageable engineering problem, not an inevitability, and deserves a calmer historical perspective rather than doom framing.
