> Frankly, I don't really see how it isn't solved, even with the current state of LLMs. Frontier models can write, understand, correct, and optimize code in practically any language at a superhuman level.

It isn't solved because they cannot, in fact, do what you claim. LLMs write code worse than humans do, even "frontier" models.

Yup. Something the article points out is that they write code better than a few, some, or many humans do - with that list below the six fingers, and how that correlates to whether one is part of the "coding is dead" crowd.
