The MVP truism IS true. Of course the MVP is not an end point, and I have never heard it suggested as such, it is a starting point.

In a simplified, world product market fit IS seen as an endpoint prior to scaling. Still once you are scaling it, you must find new products to become a sustaining company. I agree that second statement is often omitted.

That said, these truisms remain quite important. Over building your first product attempt, and premature scaling are still very very common S. valley failure modes. I suspect you have different experience, simply because you are intersecting businesses at a later stage when these early rivers have been crossed.

These truisms remain very critical warnings for the earliest companies before they ever get to your shores.
