Do we have Lego for anything else ? I mean, Lego, the toy bricks, they are great as toys.. Maybe even simple for mechanical prototypes, but I don't suspect for really clearing any new ground ? Mostly "Look, I did that thing.. but in Lego!" But, outside of maybe mechanical prototypes.. Are anything being made and shipped, that's not a toy, that uses Lego ? Who's using Lego in production? If not, why expect the metaphor to hold up for code, when it does not even hold up for Lego itself ?
