AI coding tools are real. The 2-3x speed gains are real. But faster coding doesn't automatically mean faster learning—and learning is the actual bottleneck.

In my latest post, I break down why most teams are optimizing the wrong thing, and how vertical slicing (shipping thin, end-to-end features instead of fat horizontal layers) is what actually turns coding speed into product value.
