If I were a prince, I would hire or buy a private literary tea-pot, in which I would steep all the leaves of new books that promised well. The infusion would do for me without the vegetable fibre. You understand me; I would have a person whose sole business should be to read day and night, and talk to me whenever I wanted him to. I know the man I would have: a quick-witted, out-spoken, incisive fellow; knows history, or at any rate has a shelf full of books about it, which he can use handily, and the same of all useful arts and sciences; knows all the common plots of plays and novels, and the stock company of characters that are continually coming on in new costume; can give you a criticism of an octavo in an epithet and a wink, and you can depend on it; cares for nobody except for the virtue there is in what he says; delights in taking off big wigs and professional gowns, and in the disembalming and unbandaging of all literary mummies. Yet he is as tender and reverential to all that bears the mark of genius,—that is, of a new influx of truth or beauty,—as a nun over her missal. In short, he is one of those men that know everything except how to make a living. Him would I keep on the square next my own royal compartment on life’s chessboard. To him I would push up another pawn, in the shape of a comely and wise young woman, whom he would of course take,—to wife. For all contingencies I would liberally provide. In a word, I would, in the plebeian, but expressive phrase, “put him through” all the material part of life; see him sheltered, warmed, fed, button-mended, and all that, just to be able to lay on his talk when I liked,—with the privilege of shutting it off at will.
— Oliver Wendell Holmes, The Autocrat at the Breakfast Table
Sounds to me like what he wanted, nearly two centuries early, was an LLM. He doesn’t want an encyclopedia set, he wants a personality. A model with a customized system prompt. The one part that now seems obsolete is the enormous infrastructure required to keep the thing running. Holmes must house the critic, feed him, provide his clothing, and procure him a wife. OpenAI has simplified the interface somewhat, though the data centers are arguably the modern equivalent of all that sheltering, warming, feeding, and button-mending.
