If 10000 modern people don't bring anything, how long will it take to build a mobile phone back to 100000 years ago?

It's good to be alive. What kind of bike do you want [covering your face]

65438+100000 people only need 500 opticians, 500 chemists, 500 mechanics, 500 electronics, 500 metallurgists, 500 fortune tellers and 7000 managers in various professional fields. Those 500 fortune tellers are very important! Is the key to start the source of funds! As long as there is enough money, these 7,000 managers should be able to co-ordinate at least 70,000 people to participate in every link of this chain to toss this matter. It is estimated that a prototype should be produced in 65,438+000 years [laughter].

First of all, there is no problem with the knowledge reserve owned by 65,438+100,000 people. What is lacking is the superposition of modern manufacturing tools and technologies. This problem can't be solved in a short time.

After finishing this problem, I closed my eyes and thought it over carefully. In my mind, there are 1000 modern people without anything. They crossed into the wild state of ancient times, where wild animals were everywhere, thorns were everywhere and weeds were everywhere. Survival is difficult, and food and clothing can't be solved. How can they be in the mood to make mobile phones? I feel that my question is naive, but I feel that with the IQ of modern people, it takes three generations of efforts to build a mobile phone back to that era. Why do you feel this way?

Solve the problem of food and clothing in one or five years.

For modern people who are used to comfortable life, returning to that environment is simply a hell on earth. They drink some streams and eat some wild fruits every day. They are afraid of it. They should always be careful of the wild animals that bother them at any time. No house, no clothes, big temperature difference in bed. Only the dew at night makes people wet and shivering with cold. In addition, modern people are used to eating hot soup and hot water every day. Suddenly,

With so many people gathered together, the nearby resources will soon be snapped up. Migration and vagrancy are not the way. With the intelligence and wisdom of modern people, it is certain to spread out and live. Every 200 people will build huts and settlements for a group, and then work together as a family. Some people will be responsible for security, some will be responsible for hunting, some will be responsible for taking care of the elderly and children, and some will be responsible for collecting edible wild vegetables or paddles. Let's work together and share the responsibility.

With people's physical quality, courage and survival ability in the wild, hunting is as difficult as landing on Mars. Living animals such as antelope and bison can't be caught, so they can only hide to watch tigers and lions feed, and then secretly pick up the remaining animal carcasses after eating, but at this time they must be quick, otherwise vultures, wolves and wild dogs will be surrounded and must race against time for the remaining meat.

After a long time, people began to adapt to this environment and began to make simple wooden tools or farm tools, find seeds, reclaim land and plant crops. This process takes about five years, and people can solve the hunger problem.

Second, realize industrialization in 20 years.

Agricultural production has been solved, and food and clothing have been solved. Only those with knowledge and ability can make room to study mining problems. At present, most people have production and operation experience in various factories. In addition, in ancient times, there should be considerable reserves of coal, iron, copper and other minerals on the surface of the earth. First, some open-pit minerals should simply develop and smelt some simple and practical tools, such as shovels, sickles, kitchen knives and plows. After the technical capacity is reserved, the scale of planting, mining and smelting will be expanded.

Production capacity has increased. With the support of mining and steel bars, the living conditions have been improved, and the urban system has been initially established, which can liberate some people to engage in industry. With human resources, we can improve the level of metal smelting and lay a good foundation for the completion of initial industrialization.

With high-quality steel, we can produce and process all kinds of transportation tools, improve transportation capacity and further save labor. Set up an oil exploration team to provide energy guarantee for the next production of automobiles. During this period, we will focus on the research and development of power and chemical industries, laying the foundation for the next step of industrialization. With oil, electricity and various processing and manufacturing industries, the initial industrial system has basically taken shape, and this process will take about 30 years.

Third, March into the field of modern cutting-edge manufacturing.

With the industrial foundation, overtaking in corners directly spans the steam engine era, and the internal combustion EFI technology has tackled key problems, making by going up one flight of stairs, the productivity and basic industry, move steadily from the industrial era to the electrical era. Sprint to the high-tech industry and do a good job in precision instruments, semiconductors, electronic components, integrated circuits, precision optical instruments, etc. , to lay the foundation for manufacturing chips, focusing on research and development in mask aligner. With the advent of the electronic age, smart phones can't be made, and it's not a problem to be an old man-machine with only talking function. About 25 years is enough.

Ten thousand modern people didn't take anything. Back to 654.38+million years ago, it was possible for three generations to work hard for 60 years to build a simple old man-machine machine. Never underestimate the wisdom and ability of modern people. Science, technology and development are endless. Maybe hundreds of years later, humans will drive a spaceship across the universe like we drive a private car today.

Who will go there? At least the distinction of age, sex, major and responsibility should be considered. This was 6.5438+0 million years ago, not 5,000 years ago. We should take into account the reproduction of the population and the continuity of this work, such as the ratio of men to women and the age ratio of the population. Also consider which experts are needed to make mobile phones. If they are all ordinary people, the study time will be extended for a long time. Then you need to bring some doctors, top management talents and so on.

Finally, the topic itself is a mobile phone. Make a phone call first, then make a phone call, and it will soon become a mobile phone. This is easier. Finally, smartphones may take a little longer. There are many and complicated fields involved here.

It's great to be able to carry on the family line alive!

See a friend said to 1 ten thousand years! That's not true. You think it's 10000 gorillas going back to evolve? All the accessories needed for mobile phones were also developed in the last hundred years after the industrial revolution! And it is such a complicated process from 0 to 1! I think we should bring 1000 experts of all industrial products, and the remaining 9000 are responsible for living coolies! Basically, just follow the process and it's ok! It doesn't take 30 years to build a mobile phone. Just like playing!

That depends on what kind of knowledge reserve, ability category and knowledge structure 10000 modern people are. The general meaning of the title should be 654.38+00,000 ordinary people. Even ordinary modern people have generally received higher education, and of course there are many people who have mastered the knowledge of radio communication. The key is the lack of spare parts, starting with the most basic metal refining. This process takes 10 years, almost!

My answer is, 10 years, it is expected to make mobile phones from scratch. Of course, I'm talking about the most primitive mobile phone that can meet the basic wireless call function. As for the development of 5G color screen smart phones, it may take 30-50 years.

To build a mobile phone, you have to build a monitor, a battery chip, a memory camera, a system, a keyboard, a wire, everything you can and can't see. This is not a cell phone. It's all the crystallization of modernization, brother.
