Why compare us humans to flies and vultures? It's because our biology and chemistry are in their "infancy", and so far scientists don't know exactly whether two organic molecules will react.
But we have invented many amazing technologies, such as the atomic bomb, the hydrogen bomb, electrical appliances, electronic devices, and many other breakthroughs, and we have learned to use the energy provided by the Earth, the energy provided by the Sun, and even the energy provided by the atoms, but these are not guaranteed to keep the flame of humanity alive when there is a big disaster.
From the material level of construction technology, there are thousands of cities on Earth, their scale and size aside, let's talk about the materials used to build them - nothing but reinforced concrete, the source of cement is limestone, and limestone is the evolution of the skeleton of an ancient creature. Without the generosity of ancient creatures, we would not have the densely populated cities we have now, and if we don't upgrade our industry to the level of "space mining, fusion power generation, and factory farming," no matter what we do, we'll still just be "eating" the bodies of ancient creatures. We're still just "eating" the carcasses of ancient creatures, no matter what we do.
PS: We have been using cement as a building material for more than a century without understanding its exact composition, and even today's civil engineers don't understand the effect of CO2 on concrete (CO2 has a corrosive effect on cement), so how can we say that we are technologically very advanced? Let's just say that our building capabilities have only advanced somewhat in terms of speed and design, but as far as the durability of buildings is concerned, this really hasn't evolved much. So far, almost no building is free of reinforced concrete.
In terms of access to energy, so far our civilization has been built on fossil fuels.
Some say we invented electricity. Electricity has made our lives easier, and our technology has advanced even further. But all of our industries are still dependent on the earth's biosphere, for example, the electricity we use, in addition to a part of the solar energy is converted, most of the rest of the electricity is provided by coal-fired power plants, and coal-fired power plants burn carbon, carbon is evolved from the bodies of plants in ancient times. Then there is the fact that the oil and gas we use are all variations of ancient animal carcasses, and even the oxygen used for combustion almost always comes from cyanobacteria in the oceans. In a nutshell, the reason our society has survived until now is that we have been utilizing "marine microbial waste gas" and the corpses of ancient plants.
From the point of view of the food that feeds us, it is hardly ever made directly in factories, which are only responsible for processing it, but the source of the food still depends on the Earth. If we were to leave the earth and move away from the living world, it would be almost impossible for us to survive for long periods of time, because food would not be guaranteed. The food that we usually fill our stomachs with comes from the plants, animals, and microorganisms of the Earth, and so on. So we get all our food from the living things themselves, there is no other way.
Our agriculture is still a state of dependence.
We may have made some breakthroughs in agriculture: for example, we have relied on genetic hybridization to increase yields, mechanized production efficiency has improved, and we have invented greenhouse cultivation to obtain anti-seasonal products. However, it is undeniable that human beings until now have not been able to synthesize and manufacture organic matter directly to nourish ourselves, and to make the organic matter we want like a factory. We can't control the rate of plant growth, and all crop cultivation still relies on natural photosynthesis, requiring sunlight, water and soil. Farmers are still limited by the forces of nature. In this way, our agricultural technology today is not fundamentally different from what it was 10,000 years ago, when we were just entering an agricultural society.
Imagine if in the future a "great drought" or "great flood" destroyed more than half of the world's arable land, resulting in a reduction in food production and a failure of harvests, and few countries would be able to sustain themselves for very long.
Or if an asteroid hits the Earth one day, the dust from the impact will block the sunlight, and without the sunlight, plants will die first, followed by herbivores, then carnivores, and finally the human race will die out. The end of the dinosaur era is a good example. Even our present-day agricultural technology cannot save mankind, and it is very likely that the tragedy of the extinction of the dinosaurs will be repeated. This is because the earth's ecosystem is very fragile, and we humans are particularly dependent on this ecosystem. With today's technology, we still can't seem to live off the planet.
So what kind of technology is considered advanced?
When human beings are able to get rid of the fate of eating by the sky, when all the food can be synthesized in factories, when our food is almost free, when human beings no longer rely on Mother Earth's gifts, when one day we can take our own colonial spaceships to leave the solar system and can travel throughout the cosmic oceans, then perhaps we can be considered technologically advanced a little bit because in the dark forest of the universe, the crisis is so great that we are not able to escape from it, but we are able to escape from it, because in the dark forest of the universe, the crisis is so great that we cannot escape from it. In the dark forest of the universe, there are many crises, and we are not the only ones who have advanced technology. When we get rid of the asteroid impact and the danger of human nuclear weapons, how to go in the vastness of the universe to avoid those unknown dangers, but also need us to step by step to explore, when we approach the truth of the universe, we have to become the God of the universe when perhaps we really take off the hat of the primitive technology.
Last year, mankind *** with the face of the first wave of attacks from nature - the new crown virus. It is the product of Fort Detrick laboratory or not, or the product of nature or not, in any case, it came to mankind, mankind from the beginning of the disdain, become nervous. So advanced medical technology, in front of a tiny virus so unbearable, which does not prove that the human race is technologically advanced.
Perhaps, when one day we are not worrying about the sky, no longer fearful of the time, is really mastered the technology, when the mastery of the truly advanced technology, you can shout: "My life by me not by God!"
