To put it bluntly, if your mechanical body wants to achieve the ability of a bomber, you only need one bomber. Even if your living body can do it, you should bring your own aircraft factory and refinery. Because most people know nothing about machinery and biology, there is an illusion that biology is not as good as mechanical silicon-based biology. Equal to many definition errors, such as robots. Most people don't know that corn leaves contain silica. Yes, it doesn't calculate the efficiency of the internal combustion engine. It has a backup now. Because mechanical promotion means that I don't have cow genes, promotion means that I have cows, which will be discussed separately below.
To say the least, even if you have a wide variety of protein materials, the strength of your power fiber will be the level of spider silk protein, and your glands will secrete ceramic materials to form a combustion chamber. Enough power, but also rely on genetic instructions to let the organism metabolize itself. Yesterday, it was said that it was not as good as power fiber production line, power fiber production line. The engine production line has an engine, which is convenient for you to assemble directly. If you put them together like this, you can also be called a creature. Is this an inappropriate machine? It is not that genetic modification is unacceptable, but the upper limit of genetic modification is too low in principle, which is too low compared with mechanical improvement. Don't think that you can emit lasers and throw flying cars through genetic modification. Even if there is a way, what can two or three thousand calories of rice and bread do that day? There is no essential difference between mechanics and biology at the nano and molecular levels. Hemoglobin is also a nanoscale oxygen transporter. Please note that this is about organisms, not genes. What's wrong with genetic modification?
Second, there are two kinds of flying in people's minds. One is artificial limbs, which are abundant in Cyberpunk's works. Steel bones and iron bones are extremely powerful, hiding swords and guns; The other is uploading consciousness, uploading consciousness to the Internet, changing the body at any time, or simply living in a virtual world without a body. Is it necessary to reflect this? No, whether it is useful depends on whether it is needed in reality. Prosthetics are not needed. In fact, you can't bring a knife and a gun to the street at will. America is not that free. Unless you want gangsters, Venus weapons will definitely be restricted. Seriously, there are really many people going. In reality, it is useless to yearn for life and death to go to the battlefield. Does your logistics have enough electricity or oil? Can I use the nuclear tank? However, it is generally useless. You don't need artificial limbs to move bricks. Forklifts are obviously easier to maintain than artificial limbs. The only function may be a bodyguard, but that position is too few.
If you have money, you don't need to support yourself. What can your body do? Physical invasion of the atmosphere may be possible, but in order to install X, only the brain is left. Most people don't do this, let alone be replaced by mechanical bodies, which are not physical bodies. Don't try to fly every day, not to mention that private jets are better maintained and there are many no-fly zones, especially in cities. Drones can't fly blindly. Then there is energy. Low formalization means that you need two sets of energy. This kind of energy storage mode with small volume and large energy is not easy to find. Nuclear batteries are really not that strong. Strong, so small, concentrated nuclear materials are much more expensive than slow ones. Not to mention wireless power transmission, you can't transmit a lot of energy wirelessly unless you want to bake it yourself. Regeneration of broken limbs, self-healing of diseases, immortality, bursting muscles, superior intelligence, bulletproof body, wings on the upper part and fins on the lower part, and the ability to become a catwoman. Is it necessary? Yes, it's big. There is no dispute about the regeneration of severed limbs and the self-healing of diseases. Everyone wants it, and everyone has this demand. This is the progress of medical orthodoxy, not an episode. Immortality is the pursuit of many people. If you deny this, you must also deny the meaning of consciousness upload.
Third, intelligence, physical strength and defense are no different from artificial limbs in effect, but they are very different in realization because they don't need surgery. Wings and fins are useless, just like artificial limbs, beautiful, useless and not demanding. The real demand must be pursued by the public, not self-mockery or extravagance. ? It may be easier to grow cat ears. At this time, some people want to say that the upper limit of aircraft flight is infinite, which is stronger than genetic improvement. Actually, it is not, because biology is a nano-machine, and it is the apex of the machine itself.
The biggest obstacle to gene promotion is ethics, but this ethical obstacle is actually not that big. The ethical obstacle of gene promotion is definitely less than the upload of consciousness. Secondly, organ transplantation has become commonplace, and ethics is for survival, not the other way around. Therefore, the demand for mechanical improvement is insufficient, the cost performance is poor, and the theory is lacking. Nobody does it in reality, but the demand for genetic improvement is strong, the cost performance is high and the theory is perfect. Some people are already studying it. In this comparison, you will find that mechanical promotion is not easy to be accepted by real people, and genetic promotion is rejected only because they don't need it for the time being. You just need to ask those who are physically damaged if they want the original version or the mechanical version.
The next acceptance level is incomplete flight, using exoskeleton and partial prosthesis and replacing some fragile organs. But incomplete flight is actually useless to ordinary people. Further down is genetic modification, which involves real scientific and ethical issues, but it also has many supporters. It can greatly improve the living standards of ordinary people, second only to the magic spirit flying. Finally, the most difficult thing to accept is the canned food in flight. A simple fact is how to upload consciousness. After uploading, the new consciousness claimed that it was you in the past, but did you transfer or kill the copy in the past? Nobody knows. Just like the necromancer with a hammer of 40k, it looks like a canned plane, but it's all extinct, leaving only some machines with memory and consciousness. In addition, canned food will significantly increase the government's control over individuals, reaching a level of control unimaginable by the most extreme big government supporters in the past, so it is almost impossible to support a complete plane.
