The Fallacy of the Almost-General-Purpose Computer
The Fallacy of the Almost-General-Purpose Computer writes Edward Felten. I get the impression I would know exactly why if I could put the correct pieces together, but I can't lay hands on them right now. Has anyone written well about this on the Internet?

From the piece:
If you're designing a computer, you have two choices. Either you make a general-purpose computer that can do everything that every other computer can do; or you make a special-purpose device that can do only an infinitesimally small fraction of all the interesting computations one might want to do. There's no in-between.I can tell you that this is true. And I can assure you that every well-educated computer scientist knows why it is true. But what I don't know how to do -- at least not yet -- is to give a simple, non-technical explanation for it. If anybody has a hint about how to do this, please, please let me know.
