Yesterday, when I taught my child to "hound", I thought of GreyHound ("Greyhound"), and then I thought of the film - Sully.
I realize that the first association is from the word itself, but the second is from Hanks, from a good impression of the character he made and his own bearing. So I rewatched the movie before going to bed and then flew overnight.
An understanding of the film can begin with this quote from Sully at the final questioning session, when he said:
"You are looking for human error, then make it human."
With this sentence, we can see the core of the conflict that this film shapes: when people save a crisis in a certain way, but we still have to check whether this way is optimal - the control group is artificial intelligence. Here, although the word AI never appears in the movie, all the computer simulations and calculations are actually—at least a weak artificial intelligence.
For the answer to this question, the film finally draws two conclusions. The first conclusion, if you look purely at the problem of calculation, then Captain Sully did not actually make the best choice. His plan saved everyone, but caused huge economic losses; the second conclusion, if you take into account In fact, all the possibilities of any person's psychology, physiology, experience and emotion, considering that no one has ever encountered this situation and therefore no one has received any such training, then the computer simulation is purely an afterthought or It is "standing and talking without back pain", Captain Sully has actually made the optimal solution in just 208 seconds.
So the final conclusion of the investigation is: "it is extraordinary" - Captain Sully, you are awesome.
This is the end of the one-and-a-half-hour movie, but the memorial can continue: What is the core difference between computer operations and human thinking?
Of course, this question is very large and meta-question in nature, and it is far from a commercial film; but I think there is still a special value in continuing to explore this film because it reveals a very critical point in answering this question. .
Please go back to the movie again: according to the logic of the story, the crux of Sully's argument, no matter how eloquently he speaks in the scene, but as a system of high trust in computer computing - even we might say the current human beings who highly trust digital computing The world, the words of man, noble or not, must finally be turned into a parameter and then recalculated - there is no unfairness in doing so, after all, if there is no computer, if nothing else, just design and manufacture this turbine Advanced airliners with turbofan engines are impossible. Then, we see that the modified parameter is actually time: add a delay of 35 seconds; and then we see that the optimal solution of the computer simulation no longer holds.
Special attention needs to be paid here. In fact, the computer here does not really recalculate the entire scheme under the premise of a delay of 35 seconds, otherwise the computer may give the same choice as Sully. So those 35 seconds are not so much the reason why the computer can't be as successful as Sully as much as the reason why Sully can't be as successful as the computer.
Sully's request to join HUMAN is actually a request to join human limitations, and the story seems to imply that the essence of human limitations is that he (she) is an existence that occupies time .
In this regard, the weakness of human beings compared to computers lies in his diachronicity, in his "slowness". People's words should be said one by one, very slowly, and people's thinking, thinking, and calculation should be carried out little by little, very slow.
However, this is man, and, as it happens, man—the much slower man who invented a computer faster than himself.
Does that mean we can use computers to scold people? It's like, when we use a fire stick to successfully stab a fire, does our hand become a waste that is even worse than a fire stick?
Obviously not.
The speed of computers is premised on the slowness of humans. In fact, only human beings can really identify the speed of a computer. The "fastness" of a computer is originally expected by human beings to be "slow", and its "fastness" reflects the purpose of human beings . So, if you were to ask why humans are so slow, the answer is that humans need to choose priorities—that is, ends—by his preference from nature, which has no priors at all.
In other words, humans make choices and care about purpose, while computers do not. Choices are time consuming, and two clumps of delicious grass can starve a donkey that is only rationally hungry. The purpose is fundamentally irrational, and the purpose is not computationally necessary.
In this regard, the limit of artificial intelligence, the fundamental criterion of the Turing test, is whether the autonomous existence of "purpose" can be detected. Human "wisdom" lies in his complex grasp of "purpose".
However, as Lao Tzu said: Wisdom comes, and there is great falsehood.
The purpose must bring about the shielding of one purpose from the other purpose, and this shielding has no logical continuity at all, and, according to some simple understanding of Gödel's law, it is this lack of circumference that constitutes a purpose. the full sense of human life.
But please pay attention to the real meaning here: people's words with purpose are more or less a "lie"; those who can lie are people.
I can't help but think of another movie: "Ex Machina" (Ex Machina), a thriller, the core of the story is when the artificial intelligence will finally lie, and when "she" catches up with those 35 seconds, or rather, she starts Hesitating for those 35 seconds, when she starts to really think, humanity is in danger.
We see in the movie that the inhumane committee has to question the hero Sully suspiciously. In fact, it is a sound embodiment of a system. Humans cannot be trusted and must be cross-examined. In this sense, the final approval of the captain by the questioning committee may be expressed as:
Mr. Sully, now we believe that you fully represent the kind of excellence in human beings, because you are a role model in the world in terms of skill and especially integrity.
Sully.
