> In my experience, about one third of the time the toy is all you need, you can stop there, and what you were going to build fully would be over-engineering.

On the flip side, the cases where the toy ends up being promoted to production service end up being riddles with technical debt, missing features, and buggy behavior that jeopardizes the whole project, also happen.

Survivorship bias is also a major problem. It's easy to presume that the winning bet you took is the right path.

This scenario emerges as often when starting from the toy as it does starting from the "correct" full implementation.
