Moving fast and breaking things is something toddlers do.
Please start acting like responsible adults.
Responsible adults can also move fast and break things when they are testing in a hardware-rich environment. There's much more information retrieved from something breaking than when something works the first time.
When something breaks, you learn the limits of a specific design. When something works first time, you only know a specific design works in a specific environment - you don't learn where things will break in the design.
