I'm not arguing that they cant write code, or write a proof. Its just not written or designed well and is absolutely brutal and soul crushing to work with. Look at these proofs they're producing also, they're millions of lines of Lean that are impossible to reason about.
The way we're using the term 'verticle' to describe a curve means we're not being honest about this. This curve can actually be plotted, you can go look at the curve. It is not in fact 'verticle'. Each model release is climbing single digits on benchmarks it was overfit for.
