The team is impressive, I was wondering what all this new internal language, 400 macros, etc., could be put towards, thinking they were stuck in over-engineering. But after seeing that promise for their app, I changed my mind. Something that’s capable of making you 100 times more productive probably does need that level of development.
I don't know even still if efficiency is correlated to lines of code in a product. Sure maybe a weak relationship at best, but the scale of the software does not necessarily mean it will be any more useful than something else.
I don't think twobitshifter's point was that "more code === better product" either but rather that if it's a product with big scope, it probably has more code in it than if it was a product with narrow scope.
