On the planet Earth, man had always assumed he was more intelligent than dolphins |
|
because he had achieved so much -- the wheel, New York, wars and so on -- |
|
while all the dolphins had ever done was muck about in the water having a good time. |
|
But conversely, the dolphins had always believed they were far more intelligent |
|
than man -- for precisely the same reasons. |

the state of technology at any time is as complicated as it possibly can be |

if something can be added, it will. |

the creation of a new market, free of any of the difficulties associated |

with the unpleasant business of software development: UML books! UML |

courses! Courses on the books! Books on the courses! Books on the books! |

Introductory courses to prepare for the advanced courses! Courses for those |
|
who teach the courses! Revisions! UML journals! Conferences! Workshops! |

Tutorials! Standards! Committees! T-shirts! The more you think about the |

possibilities, the more dazzling they look. And for any reader brave or |
