Those Who Swift - Issue 211
Weekly note ✏️If you’ve been noticing that AI-generated results are feeling a bit… off lately—you’re not alone. In fact, even OpenAI recently acknowledged that newer updates have shown degraded performance, and they don’t exactly know why. But here’s the thing: AI researchers and engineers might have a few clues. One of the biggest challenges in AI progress has always been training data quality. We’ve heard for a while that high-quality, human-written, and licensed data is in short supply—and now we’re starting to feel what happens when that well runs dry. Once the systems chew through most of the good stuff, what’s left is often lower quality or even AI-generated data—and training models on AI-written content is like making a copy of a copy of a copy. From my own experience over the past two weeks, I’ve seen some clear signs of this degradation. A popular AI tool returned five different On the bright side, this forces us to review generated code more carefully, since it no longer compiles straight away. But there’s a deeper issue:
And that’s dangerous. It erodes trust. The lesson here? As AI shifts from shiny new toy to daily dev tool, we need to stay sharp, validate every line, and recognize that we’re not just using AI—we’re shaping how it’s used, and what standards it has to meet.
