No question, particularly in Arizona. The lack of rain makes it "older" on the surface, less erosion. I would love to build a giant metal detector and go searching for meteoroids and the like. I lived in Phoenix and miss roaming around the govt. land, which is plentiful, so there isn't anyone to ask permission. Just do the roaming in the winter, which is very mild, bring lots of water and curiosity. The mountains are climbable and everything is fairly accessible. You can bet most every day will be sunny and clear.

If Yahoo ends up holding the private keys, then it's completely untrustworthy and useless.

Let's hypothesize that Yahoo does this the worst way possible, so we can play to everyone's fears. Let's say the users aren't even going to have the key on their machines ever, and instead, Yahoo explicitly announces they have your private key, and their server will do all the decryption and signing for you (your machine won't even be doing it in Javascript), and they're under US jurisdiction and therefore subject to CALEA and NSLs, and furthermore just to make things worse, let's just say that they even publically admit that they would happily provide keys to any government who asks, without even a warrant or sternly-worded letter. But when you ask 'em if they really mean every government, "even Russia?" they reply with "no comment" so you're not sure they're really publically admitting everyone to whom they'll give the key.

There. Did I cover all the bases? Did I leave anyone's pet fear out?

Sorry, let's add a few more things. Let's say Yahoo's CEO is a Scientologist, all their network admins are required to be either Holocoaust Deniers or Creationists, and every employee is required to have at least 25% of their investments in MPAA companies. The receptionists all have iPhones, the corporate mission is the next president of the USA must have either Clinton or Bush as their last name, and henceforth all their web ads will be for either Amway or Herbalife. All the interns are spies for Google and Microsoft and Chinese industries, except for a few which are spies for Mossad, FSB, or Al-Qaeda. The head janitor is being blackmailed by two unknown parties for his participation in a kiddie porn network, and the top sysadmin hasn't heard about Heartbleed yet, the top programmer (who bears the title "Grand Wizard" on his business card) doesn't believe in comments, their implementation of OpenPGP uses a 1938 Luftwaffe cipher as its entropy source for generating session keys, and the company weather station's thermometer was installed on a south-facing patio that gets direct sun all day long.

You may possibly harbor doubts about trusting this company. Yet in that situation, switching to Yahoo email would be more secure than what most people have right now, with plaintext email. So how's that "useless?"

Now all I have to do is get my father, my mother, my sister, my half-sister, my grandmother, my wife, and my assorted friends to learn what PGP is and how to read the emails I send them.

You jest, but don't you see how popular webmail providers adding insecure PGP implementations to their platforms would be a pretty good first step to doing exactly what you say?

What a silly feature. Just put "Cc: BackupDood" at the top of your email, and you get the same thing.

Where did it say in there that users would hand over private keys to a third party?

It's implied by the fact that it's webmail. Does your browser have an OpenPGP library? Does it check all the Javascript that it downloads and executes, against some repository's whitelist? You have to assume the key isn't handled safely, unless you can answer Yes to these questions. And a lot of webmail users expect the server to be able to search and that's obviously impossible unless the server can read, so it's not like the unsafeness stems just from potential trickery.

That said, the more interesting question is what social effect this might have. Even "bad" use of OpenPGP could start conditioning more people to being familiar with, tolerating, expecting PGP. Get into a better frame of mind, and better habits can come later. And with good habits, some security could eventually emerge. The security wouldn't be there for Yahoo webmail users, and yet some users might end up having Yahoo webmail to thank for it.

And let's face it, the barriers to secure communication are almost entirely social; we choose to have insecure communications. Anyone who is working on that problem is working on The Problem.

There are over 30,000 deaths in the US alone in automobile accidents; even supposing automated vehicles cut that number by 90%, 3,000 multi-million dollar settlements every year would destroy the automobile industry in the US.

3,000 multi-million dollar settlements sounds like a lot of money, but the 30,000 multi-million dollar settlements that we're already paying insurance premiums to pay for, is even more. Yet the system is apparently economically viabile even in 2014 when the costs are ten times higher. A scenario where where the accident rate is a tenth, is a scenario where insurance costs a tenth, so the total cost of a vehicle is somewhat less. This would be good for the auto industry, not bad.

If you tell someone they have a choice of two cars, one where they pay $70/month to State Farm (called "careless human's liability insurance"), and another where they pay $7/month to Ford (called "careful AI's liability insurance fee", because you're not buying insurance from Ford's AI, but rather, funding its insurance), that second one is more likely to result in a car purchase.

There would have to be a "work under this title" (something copyrightable) which becomes accessible by putting in the fuse. If plugging in the fuse causes their copyrighted AC-available icon show up on the dashboard, for example, then it'd be a DMCA violation to plug in the fuse without their authorization. Also, it might become illegal to manufacture or traffick or sell fuses without Chrysler's authorization, but that's subjective and subject to judges' whims (how they decide to interpret your fuse's primary purpose, commercially significant uses, Chrysler's marketing, etc).

But if all it does is enable the air conditioner (if there's no copyrighted work protected by it), then it's not a DMCA violation.

This wouldn't ever happen, though. Suppose you made your own copyrighted work and also had it become accessible only by plugging in the exact same sort of fuse. If you became "commercially significant" enough, then Chrysler's own fuse sales to their own customers would become illegal (devices that circumvent your DRM). It's for this reason that all DRM schemes need to be trade secrets or patented, to keep different copyright holders from using each other's schemes (or at least keep 'em from doing it without a contract to cooperate). That's why no one would really use fuse as DRM. It's not that they'd worry about their customers "hacking," but because they'd need to worry about someone (anyone!) coming and suddenly making their own business illegal.
