And now we have the multimedia/communication hype: the best bits are those that just arrived from far away, and if you are not "on line", "on the Net", you just don't count, you are not of this world (which is virtual anyhow...). Apart from a change in vocabulary, it is the same hype, the same snake oil over and over again, and you can do me a favour by not getting excited by all the time you are supposed to save by switching to "home banking".
Sometimes very smart people can be mostly insightful, but very spectacularly wrong on some points.
Roslin: It tells people things like where the restroom is, and-
Adama: It's an integrated computer network, and I will not have it aboard this ship.
Roslin: I heard you're one of those people. You're actually afraid of computers.
Adama: No, there are many computers on this ship. But they're not networked.
Roslin: A computerized network would simply make it faster and easier for the teachers to be able to teach-
Adama: Let me explain something to you. Many good men and women lost their lives aboard this ship because someone wanted a faster computer to make life easier. I'm sorry that I'm inconveniencing you or the teachers, but I will not allow a networked computerized system to be placed on this ship while I'm in command. Is that clear?
But what's the alternative? Just wait until someone's sick enough to warrant a cancer screening?
Absolutely! If the statistics show that we're better off without early screening in terms of health outcomes, by all means! We should be doing something else with our time and money than to spend them on ineffective screening.
The problem with lots of screening is that on the level of the population it can lead to more harm than good overall for a lot of different diseases, because of false positives, because of our psychological makeup that we'd prefer surgery for even harmless varieties of lumps in our bodies, etc. (see detailed examples in the book). In a lot of cases it happened that screening was introduced before the effectiveness of screening was established in a trial, then later trials showed that the screening was ineffective in reducing deaths or harm.
The bottom line is that well designed trials should be conducted and based on the systemic review of those trials it should be decided whether to conduct screening or not, based on whether it's improving health outcomes or not. A lot of trials don't improve outcomes.
