    Here's what would stop any massacre in any school: an unknown number of armed teachers.

    How many deaths would there be from teachers who momentarily snapped and did something stupid? How many deaths would there be from children getting their hands on the guns and doing something stupid?

    Well, let's see, it has been legal for teachers to carry in schools in Utah for more than 10 years now, and there have been zero incidents of either of the sort you mentioned.

    It's hard to extrapolate from zero, but we can probably use it to set an upper bound. Let's suppose that an incident occurs next year, which will actually be the 12th year since teachers have been able to be armed. There are approximately 3M residents of the state, so that would give a rate of one incident per 36M resident-years, as an upper bound. So that means that we could expect at most 8 such incidents per year nationwide (again, remember this is an upper bound). As compared to observed school shootings, that would be a win, assuming the rate actually was that high, which I strongly doubt.

    I fully expect that Utah will go 20+ years without any incident of either sort. There are other states which are also in the process of allowing teachers to be armed, or have allowed it recently, and some states in which it's up to the school district and some school districts have chosen to allow it, so the reliability of our statistics will be improving over time.

    How many deaths would there be from the cross-fire during a school shooting?

    What a ridiculous argument. Which do you really think will cause more deaths, a stray bullets from armed people shooting at one another, or unopposed, aimed bullets from a rampage shooter methodically picking people off?

    Again, there's no need to guess, though, because it actually does happen that rampage shooters get stopped by other armed people, both police and civilians. On average, when rampage shooters are stopped by civilians, 2.33 people die. When they're stopped by police 14.29 people die. The difference lies in response time. The time it takes for armed people to arrive is the time that a shooter has to go about his bloody business. When an armed person is already present, rampages end quickly and deaths are low.

    And, in fact, I haven't seen a single example of a case where innocents were killed "in the crossfire" between civilian carriers and bad guys.

    Besides, the point is moot since nobody can expect an average user to sue giant corporations - given their army of lawyers.

    Class action. Or, alternatively, legislative action. Google is fully cognizant of both of those possibilities, and that at Google's size and public visibility one or both would happen.

    When I type google.com into a browser, I am not expressing any intent for Google to track me.

    Intent, no, permission yes.

    Google is simply assuming that the fact that any packets are routed through their networks gives them the right to inspect and track/save them.

    Do your packets get routed through Google's network? Not unless you're on Google Fiber, and if you are Google doesn't assume any such right.

    But you're not talking about packets which you're sending somewhere else which happen to flow through Google, you're talking about packets that you send to Google's data centers, expecting those data centers to do some useful work for you. The price for that useful work is targeted advertising and the tracking which supports it. Though, of course, Google being Google, the company does provide you with tools to opt out of that (aside: do you use the Google opt outs? I think you should, based on your expressed philosophy).

    What if every single internet backbone provider starting mining data packets?

    Sorry, but I think this is a red herring. That's a completely different situation. And, personally, I think you should encrypt all of your traffic to make it impossible for middlemen to see anything.

    What if Google decides that people who click on ads should have their traffic/service prioritized?

    Conceptually I don't see any problem with that. In practice it wouldn't gain Google anything, since any motivation to click other than interest in potentially buying the advertised product ultimately does Google no good. It increases clicks, but decreases the value of those clicks to advertisers, which in turn causes them to bid less. There's a good reason that Wall Street pays a lot of attention to Google's "cost per click" metric; higher values mean advertisers are bidding higher, which means that Google is providing more effective advertising.

    Another point to consider is that Google isn't an advertising company. Google is a technology company which has historically found that the easiest way to monetize its technology is through advertising. But Google's non-advertising revenues have been growing far faster than its ad revenues for some time now. They still only constitute 10% of total revenues, but that's up from 4% a couple of years ago.

    Once you create a successful business which relies primarily on user data/clicks/impressions - the only way to grow in a saturated market is to give the 1-2% "paying customers" who click on ads something extra.

    Actually, Google's advertising market is far from saturated. Google owns a big chunk of online advertising, but online advertising is still small potatoes compared to total advertising. There's lots of room for growth.

    And I'm not even getting to what can happen if data is used to manipulate peoples psychology.

    Interestingly enough, while I disagree with you on this point, because I'm a cold-eyed libertarian who thinks people should be responsible for themselves, the vast majority of Googlers, including Google management, agree with you, that Google could but absolutely should not do anything like that. Not that my reassurances that Google is a bunch of bleeding hearts will really give you any comfort, because that could change.

    The horrifically inefficient petrol engine still wins, it seems.

    Not with those numbers, especially not when you include the ~15% gain from regenerative braking and when you remove all of the weight of an ICE and drive train. An EV needs no transmission to speak of, and the motor is a small fraction of the size and weight of an ICE. Factor those in and while the ICEV still edges ahead of the EV, it's margin of superiority is not that large.

    And then when you further factor in the benefits of not burning gasoline... EVs are pretty compelling. Their one downside is that batteries are so expensive that getting 200+ mile range makes the cars really pricey. With smaller batteries they're very competitive -- I bought my LEAF based on pure economic analysis. Over an eight year time horizon it was significantly cheaper than any ICEV (break even at just under six years), even without the tax credits, and with the state and federal tax credits it was cheaper after two years.

    But that only works if you don't need the longer range. For me the LEAF is a perfect commuter car. Range is not an issue, and it's extremely cheap to own and operate, and a lot of fun to drive. I still have to have another vehicle for longer trips, which is fine for me because I would have another vehicle anyway. That's not the case for everyone, of course (though I think it might work well for some people to own one short-range EV and rent an ICE for the occasional long trip).

    I think privacy policies are more meaningful than you imply. I believe they create promissory estoppel.

    Well, nothing stops individual employees from leaking/spying on data anyway. And it has happened .. at Google/Facebook/etc, so all the security in the world will only stop external script-kiddies and other low-level information hackers but cant stop anyone who is motivated enough.

    Actually, there is a lot that stops individual employees from leaking/spying. The article you mentioned was three years old, and it described things that happened earlier. There is a lot of infrastructure in place today to prevent unauthorized employee access that wasn't there 3-4 years ago. I happen to know that very well, because I design and build a lot of it -- and 95% of all of my effort is devoted to internal threats. Not because we believe that there are a lot of malicious Googlers, but because if you can guarantee that insiders can't get at the data, outsiders have no chance -- and to prevent examples like the one you cited (which AFAIK was the last such case).

    Of course, you'll note that the preceding paragraph was just reassurances with no details. Unfortunately, that's because I can't provide details -- which I actually think is a mistake on Google's part, and something I regularly bring up with management. Google has a really excellent security story, and I think we should be telling it. But since we aren't all I can say is: It's awesome, trust me :-)

    So, I'd much rather the data stay in house at Google, who does a good job of securing it, is willing to fight back against government intrusion, and even gives me the option of seeing what data they have collected (through the privacy dashboard) and allowing me to opt out and/or have my data deleted. And I'd rather that Yahoo! promise to keep what they collect on me in-house as well, rather than selling it, even if I don't have quite as much confidence in their integrity.

    Your statement contains an implicit assumption that data *must* be collected. I am of the opposite view. Personal data should never be automatically collected, even in an anonymous fashion. All data collection must be done through a specific means (e.g. user submitted form) via an explicit opt-in event - not just clicking "I Agree" on some large wall of text that nobody can understand.

    We disagree on the need for an explicit opt-in, and I do think that Google's business model is a reasonable one, and one that's good for users. Google can provide the array of great services that it does because of the trade it makes with users: You allow Google to collect data and use it to target ads to you, and in exchange you get all this stuff. You are free to opt out of this deal, but, frankly, Google wants to make it such a great deal that you don't want to -- and being responsible with your data, ensuring that you know that it won't be used for any other purposes and won't leak, is an important part of the deal.

    and even gives me the option of seeing what data they have collected (through the privacy dashboard) and allowing me to opt out and/or have my data deleted.

    Maybe but why would individual user information be useful to anyone? I mean .. if I was trying to sell a product, I'd want to target an entire class of people conforming to certain criteria rather than specifically Bob or Sally.

    What you really want is the contact details for all of the individuals in that class, so that you can advertise to them directly.

    Frankly, if that were all that was done, I wouldn't care. Given that I have to see ads (or find some other way of paying for content), I'd rather see targeted ads than shotgun ads. The problem is that once the data has been sold, there's no way to call it back, and no way to keep track of what was done with it.
