Heh.

It's at the other end of the college curriculum, but I had a somewhat similar experience. I arrived at college having passed AP Calculus but without having taken any trigonometry. After a couple of semesters I realized I really needed to address my lack of trig knowledge, so I enrolled in a course. The prof who was teaching it recognized my name and asked me to come talk to her. She suggested that I drop the course and instead spend the semester grading papers for the class, rather than taking it.

I did as she suggested, and I think I learned more trigonometry than any of the students in the class.

even with fast charging, you aren't gonna want to charge ten times a day

Maybe.

Fast charging + wireless charging + ubiquitous charging stations might make it very practical. For my lifestyle a two-hour battery life with 20-second recharges from just putting my phone on a certain region of my desk, nightstand, car console, etc. would work just fine.

As I recall, the paper from Google said something slightly different. It said they found no increase in failure rate. As a result, Google data centers do run warm: 80F. The employees in data centers wear shorts and t-shirts all the time.

The problem with printed firearms is that they're plastic. We have no means to detect them. They instantly obsolete our security infrastructure. You can walk onto an airplane with one. You could walk into a courtroom with one. You could walk into the White House, Congress, or the Supreme Court with one. That is a major problem.

And banning them will do exactly nothing to address that problem.

A person who would make a gun with the intention of committing murder with it isn't likely to be deterred by a law banning his gun. Actually, that law already exists... the Defense Distributed guy was careful to epoxy a six ounce block of metal to his before fully assembling it into an operable gun, because it's a federal felony to manufacture an undetectable gun.

However, not everyone who uses guns irresponsibly are punished. For example it is legal to have an accessible gun in your house and leave your teenager alone with it.

Is that irresponsible? Depends on the kid. There are many examples of kids using guns to defend themselves and their siblings against home intruders.

All of the commentary here completely misunderstands what Page said.

He wasn't suggesting that we ought to give up on medical privacy. He was saying that we'd be better off if we could do so -- if we chose to -- without fear of repercussions. He said that in some cases being more open might be beneficial... but he clearly chose to keep his condition secret for quite a long time, even though it was obvious to everyone that something was wrong, and he didn't say anything to imply that we shouldn't have the right to privacy.

Translation: Google Big.

Yep. And there comes a point when you're scaling up that quantitative differences become qualitative differences that demand completely different solutions to the old problems.

Translation: Firmware Is Magic.

No, firmware is static, and the code it contains must fit in limited capacity storage devices and run on low-end CPUs, unless you want to pay big money for your switches. Much better to make the switch firmware simple and the switches cheap, and put your logic in a few much more powerful machines with visibility into the bigger picture.

On the range.... give it a few years. The Tesla already has a 200+-mile range (though not when racing, obviously), but it'll get better. It's also worth pointing out that the Tesla Model S in that video is not a sports car. It's a nearly 5000-pound luxury road sedan. The fact that it's even remotely competitive with a Viper which weighs 2000 pounds less, and has a monstrous engine, is very impressive.

As for sound... in the real world I really like the utter silence of my LEAF.
