Solving a critical bug in the default Rails caching library | Aha!

On March 20th, ChatGPT users reported seeing conversations that were not their own. Just a few weeks earlier I had solved a bug where the default Rails caching library (Dalli) would return incorrect values. I thought, "this ChatGPT incident sounds a lot like what could happen with that caching bug via returning incorrect cached HTML." But OpenAI doesn't use Rails so I shrugged the thought off as recency bias.
