as Twinbee hints at; it's all to do with bias
Name one other profession or trade or area of expertise where expert advice is so routinely ignored for such trivial reasons.
All of them.
It doesn't happen with doctors, lawyers, plumbers, electricians, auto mechanics or insurance agents.
You might want to talk with some doctors, lawyers, plumbers, electricians, auto mechanics or insurance agents. They'll tell you differently. It might happen a little more often to IT professionals, but, trust me, it does happen everywhere.
Having an interest in terminal ballistics, I'd like to see some citation for that. While there may be some difference between 5.56 NATO and, say, 7.62 NATO in terms of lethality, I would be willing to bet that the primary contributing factor is shot placement.
We use small calibers because it allows the soldier to carry more ammunition into battle.
Terrorists will always find a way to get explosives on planes if they feel they need to.
Why bother? Thanks to security theatre, they can now simply blow themselves up in the scanner queue, which will kill the hundred or so people packed in there, will probably shut down the entire airport, and will cause the government to rape us even harder than before.
For me the important conclusion of the book is that there is no practical way to fullfill all our current energy needs from "renewable" resources.
That's perfectly reasonable. This is a misrepresentation:
if you actually look at the physics, it is not possible to supply all our current energy needs entirely through solar and wind (renewable) power.
When you look at the physics, it is entirely possible, it just isn't attractive given the area used and the cost of doing it.
Disk crisis, please clean up!
