While I do get the "spirit" of this, I feel it's highly inaccurate and/or misrepresentative in some cases.

An example would be Javascript. Sure he implemented a prototype in 10 days, but the whole implementation was probably a fraction of the test code for V8, a modern implementation of the beast that is Javascript today. I'd even argue that the VM engines from 5 year ago would still hold the same property.
