Remember when GitHub Copilot was the only game in town? Those days feel like ancient history now. We’ve witnessed an explosion of AI coding assistants, each promising to revolutionize how we write software. But here’s the uncomfortable truth: many of these models have already joined the digital graveyard, taking millions of dollars in developer learning investment with them.

I’ve been tracking this trend for the past two years, and the numbers are staggering. Conservative estimates suggest developers have invested over $100 million in learning tools, workflows, and integrations around AI models that no longer exist or have been fundamentally changed. Today, let’s dig into this graveyard and figure out how to build skills that actually last.
