From Ferguson's The Ascent of Money:
The libro segreto - literally the secret bookf - of Giovanni di Bicci de’ Medici sheds fascinating light on the family’s rise. In part, this was simply a story of meticulous bookkeeping. By modern standards, to be sure, there were imperfections. The Medici did not systematically use the double-entry method, though it was known in Genoa as early as the 1340s. Still, the modern researcher cannot fail to be impressed by the neatness and orderliness of the Medici accounts. The archives also contain a number of early Medici balance sheets, with reserves and deposits correctly arranged on one side (as liabilities or vostro) and loans to clients or commercial bills on the other side (as assets or nostro). The Medici did not invent these techniques, but they applied them on a larger scale than had hitherto been seen in Florence. The real key to the Medicis’ success, however, was not so much size as diversification. Whereas earlier Italian banks had been monolithic structures, easily brought down by one defaulting debtor, the Medici bank was in fact multiple related partnerships, each based on a special, regularly renegotiated contract. Branch managers were not employees but junior partners who were remunerated with a share of the profits. It was this decentralization that helped make the Medici bank so profitable. With a capital of around 20,000 florins in 1402 and a payroll of at most seventeen people, it made profits of 151,820 florins between 1397 and 1420 - around 6,326 florins a year, a rate of return of 32 per cent. The Rome branch alone was soon posting returns of over 30 per cent. The proof that the model worked can be seen in the Florentine tax records, which list page after page of Giovanni di Bicci’s assets, totalling some 91,000 florins.
The Medici Bank is pretty interesting. A while ago I wrote https://en.wikipedia.org/wiki/Medici_Bank on the topic; LWers might find it interesting how international finance worked back then.
One open question in AI risk strategy is: Can we trust the world's elite decision-makers (hereafter "elites") to navigate the creation of human-level AI (and beyond) just fine, without the kinds of special efforts that e.g. Bostrom and Yudkowsky think are needed?
Some reasons for concern include:
But if you were trying to argue for hope, you might argue along these lines (presented for the sake of argument; I don't actually endorse this argument):
The basic structure of this 'argument for hope' is due to Carl Shulman, though he doesn't necessarily endorse the details. (Also, it's just a rough argument, and as stated is not deductively valid.)
Personally, I am not very comforted by this argument because:
Obviously, there's a lot more for me to spell out here, and some of it may be unclear. The reason I'm posting these thoughts in such a rough state is so that MIRI can get some help on our research into this question.
In particular, I'd like to know:
