Ostensibly, an unbiased, well-trained model would solve this because it would/could write fast, performant vanilla. As a product owner, you probably care more about the performance of the product over the specific technical implementation details.

I take that to be the point of the article: the bias towards React and of course the training data being stale means that generated code will always have a bit of staleness and as we provide less context for the AI (e.g. StackOverflow), the bias towards staleness will amplify given the large body of stale information it has ingested and amalgamated.
