I'm not saying a computer can't fly the U2, but I do think it'd be more complex than a conventional aircraft. It has some pretty unique flight characteristics. From Wikipedia:

"...To maintain their operational ceiling of 70,000 feet (21,000 m), the early U-2A and U-2C models had to fly very near their never-exceed speed (VNE). The margin between that maximum speed and the stall speed at that altitude was only 10 knots (12 mph; 19 km/h). This narrow window is called the "coffin corner", because breaching either limit would likely cause airflow separation at the wings or tail. For most of the time on a typical mission the U-2 was flying less than five knots above stall speed. A stall would cause a loss of altitude, possibly leading to detection and overstress of the airframe."

This actually sounds like the kind of challenge a computer can do VERY easily - much more so than a human.


This speed management is actually handled by an autopilot (i.e. computer) in U2s, using 'mach hold' mode.


Some friends and I have defeated a few other devices with face unlock features. It was the super technical task of finding and printing a photo found on social networking sites, then holding it up to the camera. I wonder if apple has hardened against this.


30 seconds of googling would've told you that it uses a 3D mapping camera + IR to scan your face.

So no, printing a photo found on social media won't work. 3D printing a perfect model of a face might, we'll see.


Unlikely, since they hardened their model against professional face masks.


but the market for professional face masks that can pass a faceid check just opened up.


They did mention in the keynote that they worked with photos, as well as professional maskmakers and makeup artists to prevent this


It uses a depth sensor. And they have trained the neural networks to prevent using 3d printed masks instead of the real face. I guess they are using depth-ir-powered-video instead of still photos.


Did you watch the keynote?


The best answer I've heard to this and your previous question was at a QandA with Dr. Daniel J. Levitin. His answer was to a question "Is there any music that can make everyone upset or unhappy?" His answer was that in all his research the only music that can make someone upset or unhappy, was music the listener didn't like. It's 100 percent listener preference. The same was true for music a person did like. Unfortunately, the only way we could find out if Beethoven, Chopin, or the Beatles like the music is to ask them. I'm sure we'll find both support and disdain from the music community on AI generated music. Time will tell if there is a major preference on either side.

Dr. Levitin has some really interesting research on music, but also has some great easier to read books for those of us without a neuroscience degree. My favorite is called this is your brain on music. The world in 6 songs was also a great read.

I wonder how relevant this perspective is to the discussion going on at [1]. Particularly, I am curious how people interpret the notion that a deep learning system could predict a person's musical preferences by their facial features.

Also, there are patents available for deterministic models based off of neurophysiological response data obtained from various sensors (primarily heart/pulse, galvanic capacitance of the skin, body temperature).

One model mentioned in the patent uses Nigel Osborne's INRM (Innate Neuro-physiological Response to Music) paradigm to make predictions.


"Also?" I was only bringing the subject up for discussion - I think it would be ridiculous to suggest that facial features could actually predict a person's musical tastes. These tastes change in some people from day to day or even minute to minute. People also subjectively evaluate music very differently, even when it's music they enjoy listening to.

As for those patents, I would caution against interpreting them to mean a person's musical preferences can be inferred or exploited in this way. Merely evoking a physical response is not the same as satisfying a person's preference or desire. Particularly, a physical response can happen in the absence of a person's consent to receive the stimulus, and in rape trials this is legally recognized to exclude evidence of such a physical response from being used by the defense.


I want to disagree a little on this. I won't disagree that the 'war on drugs' is out of control, largely mismanaged, and likely unnecessary. What I do want to say is I think it's a bit unfair to say "It never was about fighting drug use or preventing the harm it can do."

I think it's fair to say the funding and huge catalyst for the war on drugs started in Miami in the 80's. During this time where was a ridiculous amount of violence. Violence that occurred in broad daylight, that had no regard for the public, with weapons police didn't have access too. CENTAC was started and gave law enforcement a more level playing field, and had a huge impact on the violence related to the drug trade in south Florida. It effectively removed lots of violent criminals from the streets. Just look at the crime stats before and after the initiative, it's pretty clear there was a public benefit.

While I agree there are very unfortunate unintended consequences of the war on drugs, I think we also have to give credit where is credit is due. Lets learn from it and do something better moving forward.


I am confused here, the massive arming by the drug pushers happened only in a prohibited world. Yes, the DEA was perhaps not ready or was expecting Mr.Machine Gun to show up, but if 18th amendment and Al Capone were any lesson, they should know better.


The violence wasn't from drug users, it was from gangs fighting over profits from illegal trade. The war created that violence in the first place.

As another commenter noted, the parallel would be the rise of organized crime during alcohol prohibition.


>During this time where was a ridiculous amount of violence.

Was this violence not already illegal?

Surely brandishing a gun and firing on a public street in daylight is a crime with or without drug prohibition
