Most likely an autonomous car can react quicker to an obstacle running in front of it faster than a human can.
With the added bonus that if the computer doesn't react fast enough, it won't drive off and leave the pedestrian bleeding in the road to protect its insurance premiums or hide the fact that it's had a few drinks before setting off.
Compare that to a pair of forward facing eyes, with an elaborate system of mirrors to try and allow them to see behind the car as well as in front. Lots more blind spots, and they can only look in one direction at a time.
And there are lots of drivers incapable (at least for periods) of even managing that. The one huge benefit of this system is that it never gets distracted by something on the radio, or the phone ringing, or wondering what to pick up for dinner, or by the idiot who just cut it up. I wouldn't be surprised if the vast majority of accidents are caused by momentary lapses in judgement (there will be a lot that are caused by plain old bad driving, but over time experience, the legal system, and ultimately crashes, should weed those out).
What is this mental disease that makes people think we should fight to have billions and billions of people live forever?
I think it's called "humanity". You are right that it's cold logic, the head and not the heart, that will solve these issues, but for most people it's not so easy to divorce the two concepts; to know you have enough to live comfortably and to watch children starve.
Excellent journal entries, I'd advise anyone with a little time to go read them. On the credit front, my GF was one of the lucky ones. She'd pre-ordered Mass Effect 3 for me and when we received notification that they couldn't meet the order as they'd been refused stock (and gave us a £5 voucher to make up for it) I instantly realised we were talking days or weeks rather than months or years left on the clock for Game and told her to cash the voucher and her ~£25 of loyalty points in.
I can understand how people would be annoyed at having missed out, but on the other hand I'd be extremely wary of sinking more than you're willing to lose into any company in this economy (or in fact, in general - I hate buying big ticket items that have a long time to deliver like sofas, etc, leaving several hundred pounds invested in a company in the hope they'll be able to deliver). I can imagine a lot of those same people still have HMV vouchers/credit, for instance and will learn little from this experience.
Real computer scientists like having a computer on their desk, else how could they read their mail?
