If 10,000 modern humans were to go back 1.5 million years, how long would it take to make computers?

It will take a long, long time, at least more than 1 million years, because back to that time, the biggest problem faced by these 10,000 people is to survive and reproduce, there was nothing in that era, and when these 10,000 people died, the present memory in their brains will not continue.

If 10,000 modern humans go back 1.5 million years, maybe they won't be able to adapt to the environment at that time, and then there will be a mass death, and then they will not be able to build computers. If they can adapt and survive, it's also difficult for them to build a computer. They don't have any materials that can be used directly to make computers, and they don't have electricity.

So even if they solve these problems, it will take a long time, but this time is difficult to estimate because there may be failures in the process of building computers.

First of all, it is better for them to be undergraduates, if they are liberal arts students, they don't know anything and can never be; Secondly, if you are a researcher in this field, you first need to collect the elements, find a power source and avoid natural disasters, which will take about ten years.

It will take about 100 years to be able to rebuild a computer, which will be a rewind of the times, so it is very scary.

It mainly depends on whether there are talents in this area among the 10,000 people, and if there are any, it will be produced quickly, and if the 10,000 people have no experience in this area, then it will be very difficult.

If so many people are management talents in each industry, they can actually be manufactured in a short period of time, because there is technology and ideas.

Computers can be built in about 3 to 5 years, because only 10,000 modern people can go back 1.5 million years and make something possible.

This depends on whether there is a time limit, and whether it is just these 10,000 people to make it, or whether they are to develop the technology tree and let humans make it. If they develop a technology tree for future generations to manufacture, then it must be able to be manufactured, and it will take only a few years.

After all, 1.5 million years ago was only the Stone Age, and their arrival will greatly improve the climbing time of the human technology tree and help humans build computers faster.

But if you want them to make it themselves, then the answer is yes, they absolutely can't make it. Nowadays, the differentiation of technology has become more and more fine, and the manufacture of a computer requires research in various aspects. A computer involves display technology, semiconductor technology, metal technology, and even software technology.

If 10,000 ordinary people have not been specially selected, I am afraid that they do not even know the basic principles of computers, after all, a lot of knowledge of modern people is only in one aspect that they are good at, and most ordinary people are not engaged in computer-related careers.

And even a select group of 10,000 people would find it difficult to build a computer in a few decades.

How difficult it is to manufacture computers, you just have to look at how long my country has developed with the strength of the whole country, and until now it has not overcome all the technical difficulties, and it is difficult to manufacture computers completely independently.

This is still on the basis of the country's strong industrial system support, and countless research institutions and enterprises are conducting research and development. It was really 1.5 million years ago, when there were only stone tools, and the industrial base was equal to zero.

In this case, it is probably a problem that the past 10,000 people will survive, at that time, there was no **, no medicine, no food, no pens, no paper. Most of them probably didn't live more than a year 1.5 million years ago, and as they die in large numbers, it will become more and more difficult to develop computers.

What they want to build is not a single computer, but to improve the entire industrial system, which is by no means something that can be done by just 10,000 people.

It is impossible to build a computer, because it is so difficult that ordinary people can't do it, let alone go back to 1.5 million years ago.

They can't make computers, because these 10,000 people aren't necessarily all highly intelligent people, so there's an uncertainty.

This has to be based on their major, if they don't study computer science, they may not be able to do it.

Of course, they can make calculations, and with the wisdom of modern people, they will definitely be able to find methods and materials to make computers.

No, you can't. 1.5 million years ago, there was no electricity, and most of the materials used were stone, so it was impossible to build a computer.

Human civilization. There is a great deal of chance, maybe after 1.5 million years, a different civilization will develop, but if you want to develop a civilization similar to the current level, the time will not be less than 1.5 million years. According to this theory, if there is a devastating war on Earth, and only 10,000 people are left in the end, they will soon enter a primitive society.

And then re-develop.

Again, there is no threshold for these things, but they are very trivial and time-sensitive. It's useless if you don't keep learning about it, and most people don't have a lot of requirements for their computers. They just need to use them well.

So, 10,000 people go back in time.

The first thing to do is to make various production tools, promote the development of the whole society faster, and then pass on their own knowledge. Mathematics, in particular, needs to be passed on and is the cornerstone of science and technology. It takes several generations, or even dozens of generations, to obtain the social environment, equipment, and resources needed to produce computers, and only then can computers be produced.

Basically, you can't make it, and a lot of basic materials don't wait for you to finish and you "hang up" You want to make a computer instead of a musket.

With artillery! Of course, the simplest muskets and artillery also require more than a dozen basic materials.

You won't be able to build it for a long time. That's a lot of supporting equipment. And electricity.

You don't have to make it. Just a chip. You're going to have to build it for decades or even hundreds of years.

It will not be made, because 1.5 million years is when man has just walked upright, and the earth's environment is not yet suitable for human beings, beasts.

poisonous insects, food and even fresh water. Some of the ancestors of human beings said that they lived in the forest, and according to me, they first lived in caves to shelter from the wind and rain, and then the number of people increased, and there were not enough caves around, so they began to build shacks and other dwellings, and gradually developed to build houses. Humans are biological evolution.

As a result, the evolutionary process of living things is not very clear about how to define the standards of man, and it is even more difficult and difficult to say where the ancestors lived specifically!

Personal speculation is that it could take 200 years to make a computer. Because these people went back in time, it took a lot of time to build all kinds of machines and accessories, so it took 200 years to build a computer.

If there were 10,000 people who went back to the old days, they could make mobile phones, they could make trains, they could make a lot of electronic devices, they could make airplanes, they could make some military equipment.

They can make many things, they can make computers, computers, mobile phones, tablets, rockets, cannons, firecrackers, soap, soap, and so on.

It is estimated that it will take 50 years to make a computer, because 1.5 million years ago, there were no modern things such as electricity, transistors, and chips, so it is said that these 10,000 people have to make the materials to make computers.

Almost 1501.6 million years ago, in fact, even now there are very few countries in the world that can make computers, and Japan, with a population of hundreds of millions, cannot make the CPU or GPU graphics cards needed for computers, let alone primitive people 1.5 million years ago.

It depends on the overall quality of those people, if it is a complete system of professionals, and the development of the whole system without any cost. It takes about eight years to make the first generation of electron tubes, and about 12 years to make the first generation of transistors.

If you're a technician, it won't take long, maybe a few months to build a computer, because you need all kinds of things, so I think a few months is enough.

The first generation was destined not to make computers, they could only describe the technologies that were certain to be available to future generations, and let them complete them.

Descendants have never seen a computer since they were born, and they only know that their elders have some amazing things, such as extremely delicate shovels and extremely hard knives, which no one in the world has ever made.

The descendants of future generations will only regard the earliest group of people as "immortals with artifacts, full of ** and prophecy for the future". The history after that is the same as the history of mankind now.

Even if you can survive normally, to develop a computer, you have to borrow another 50,000 years from the sky.

The division of labor in the industrial base must have a population base, and the population cannot reach the scale and cannot be created, so the key depends on the population reproduction rate. But it is estimated that it will not be needed in 300 years.

I don't know how long it took to build computers, but after three or four generations they will become primitives, and our lives now will become myths and stories passed down from generation to generation.

It depends on what kind of person it is, for example, 10,000 people like me, it's not me who brags, if I can survive, I lose!

Don't doubt it, it wouldn't have been possible without von Neumann or Turing.

If you don't have this knowledge, I'm afraid you won't be able to make it.

It's hard to say whether 10,000 people will survive!

Why 10,000 people? All the people on the earth, in an instant, all empty-handed back to the world 1.5 million years ago, what will become of this time?

Maybe it will be wiped out in the past. Do you think it's simple to produce a computer?

Look at somebody, if you're going to make it now, the materials are all for you, and you can't build a computer, have you been making a computer chip for so many years?

It depends on who it is, and I don't think it will be possible to go back in the same way for 500 years

If it were a million people like me, it wouldn't be of much use.

Dutch technology is still used.

10,000 people, postdocs, still haven't graduated from elementary school.

Computers can never be built, computers are the product of a high degree of civilization, 1.5 million years ago the earth was still the era of wool and blood, without any industrial base.

It could take 2,000 years to make a computer, and that's an ancient and distant time. No tools, no manpower. None of them can be used, and they need to be remanufactured.

I think it will take nearly 100 years, because to make a computer, you need to have corresponding machine parts and accessories, and these need to be developed, otherwise they can't study the computer even if they have the ability
