The mobile phone is the greatest invention or the most failure?

is the greatest invention, it has innovated in the means of human payment, and now there are fewer and fewer thieves.

The mobile phone is a great invention, it doesn't bring tears, it doesn't send trembling voices to it. With a mobile phone, you can connect even if you are thousands of miles apart, and you can see each other at any time.

The mobile phone itself is innocent, just like electric lights, paper, etc., which were invented for human use, the problem is that we are too dependent on mobile phones, which has led to one by one becoming a low-headed person....

The reason why mobile phones now have so many features is because of its scalability. There are so many people in the world who use mobile phones, and there are more people who use them, naturally, everyone thinks of different functions, and some people develop such and such software, so the functions of mobile phones are becoming more and more abundant.

On Earth, some organisms have evolved to make sounds that can travel far distances, and some creatures have become extremely sensitive in hearing and can hear very small sounds. However, no matter how it evolves, the transmission of sound information is only a few kilometers at most.

In the evolutionary history of mankind, in the past few million years, humans never dreamed that their voices could travel so far.

There are some features that we may not normally think of. Today, I was in the factory to measure the diameter of a section of steel bar, but unfortunately I didn't have a ruler with me, and I suddenly thought if I could measure it with my mobile phone.

It was about the development of the telegraph, the radio. The mobile phone was developed through the groping of the predecessors. The various technical achievements on the mobile phone are related to the achievements in all aspects.

Now that science has developed, mobile phones will be invented, the times are different, science is getting higher and higher, and people's minds are getting better and better, so there are scientists who invent mobile phones.

It originated from the mobile communication technology in the United Kingdom.

That is, the fixed landline can no longer meet the needs of work and life.

The result was mobile communication technology.

Mobile phones are just mobile terminals.

is part of the system.
