Statistically the probability of any one of us being here is so small that you would think the mere fact of existence would keep us all in a contente… - Lewis Thomas

I have always had a bad memory, as far back as I can remember.

It is conceivable that we might be able to provide good medical care for everyone needing it, in a new system designed to assure equity, provided we can restrain ourselves, or our computers, from designing a system in which all 200 million of us are assumed to be in constant peril of failed health every day of our lives. In the same sense that our judicial system presumes us to be innocent until proven guilty, a medical care system may work best if it starts with the presumption that most people are healthy. Left to themselves, computers may try to do it in the opposite way, taking it as given that some sort of direct, continual, professional intervention is required all the time, in order to maintain the health of each citizen, and we will end up spending all our money on nothing but this.

We hanker to go on, even in the face of plain evidence that long, long lives are not necessarily pleasurable in the kind of society we have arranged thus far. We will be lucky if we can postpone the search for new technologies for a while, until we have discovered some satisfactory things to do with the extra time.
