Yes, it is the inevitability that strikes you. So what should we do about it? Just using more and more computer power doesn’t sound like the right answer. In relation to the financial services industry, Mr Rodgers has an interesting idea. “What about a special class of regulators?” he asks. A layer of risk cops, experienced bankers who prowl the building looking into anything that smells as if it is going amiss. Expensive, of course, but then we are told that a lot of the older generation want to work longer so here is a really valuable way in which they could be used. Senior regulators could stalk the banking halls, attending meetings, chatting at coffee machines, etc. Their role would be to pick up the vibes which the computers would miss.
