That's the key thing. You don't know until you put people in front of what you're building, to understand if you're actually solving the problem. Or even if the problem you're aiming for is the right problem. Hence you want a non-verbose and simple program that is easy to adopt to changes you want to make. Verbose languages that enforces you to be very strict, doesn't allow itself to change as much as a non-strict one. You're right that it's more error-prone, as you don't have the same guarantees. But in the beginning of launching something new to the world, you are gonna need to focus more on what needs to change, rather than how correct something is.
