Speaking of "Doraemon", I believe you are all familiar with it, "Doraemon" was released in 1970, and the comic has been serialized for 26 years. In the plot, Doraemon took out more than 1,300 mysterious props from his pocket. Time machine, bamboo dragonfly, arbitrary door...... It is the childhood dream of countless children.
Half a century ago, the author's rich imagination made Doraemon the originator of science fiction comedy comics, but it is precisely because half a century has passed, unconsciously, some of these more than 1,300 props have really come true.
Time machine
Among Doraemon's props, the time machine is undoubtedly the most sci-fi one. This amazing machine is capable of taking us on a journey through time and space, back to the past or the future. Through the time machine, Nobita and Doraemon not only meet their deceased relatives and witness the changes of history, but also are full of expectations and imagination for the future.

Nowadays, AI technology is becoming more and more advanced, and it is not difficult to use AI to "resurrect" people who have passed away and reproduce their voices and smiles.
Previously, the People's Daily released a short video of the centennial edition of the founding of the party "Dislocation Time and Space", in the short video, there were restored images of 10 martyrs, and the most exciting thing is not only the restoration of the images, but more importantly, their faces moved.

During the production process, technicians used a series of artificial intelligence technologies combined with hand-painting to restore the blurred faces in the old photos clearly, and also colored the old photos of the martyrs. However, since old photos are blurry, there are many steps to be taken to restore them. First of all, using the AI project "GPEN", the blurred face is turned into high-definition and converted into color, and then some hand-drawn refinement is done based on historical materials, and finally AI is used to restore the texture of the skin.
When you see old black and white photos of martyrs, many people may think that they are historical figures far away from them. And this time, they are smiling behind the AI restoration, which makes us feel that these revolutionary martyrs are alive and no longer cold names in textbooks. Isn't this a different kind of time travel?
Bamboo Spider
The Bamboo Dragonfly is one of the classic props in Doraemon, and whenever Nobita and his friends wear it, they can take to the sky and soar into the sky.

Nowadays, as one of the hot spots for the development of new quality productivity, the low-altitude economy, together with commercial aerospace, biomanufacturing, and life sciences, has been included in the government work report for the first time and has attracted much attention. At present, occupying the C position of the low-altitude economy is a new concept of transportation called electric vertical take-off and landing (eVTOL), that is, electric vertical take-off and landing aircraft, which has a less accurate but better understood name - flying car. Despite the name "flying car", the vast majority of eVTOLs don't look like cars, and it might be more accurate to call them "electric helicopters" instead.

In the 21st century, technological advances in the field of batteries and electric distributed propulsion have made the appearance of eVTOLs, which can hover, take off and land vertically, and do not require an airport. Because electric motors are far smaller, cheaper, and more responsive than internal combustion engines, multiple engines and propellers can be installed on a single aircraft to achieve distributed power.
Perhaps, in the near future, the sci-fi vision of "flying" with a few clicks on the mobile phone will shine into our real life.
Any door
A pink door, every time you open it, you can instantly go anywhere you want to go and start a new journey.

So, in reality, is there such a door?
I believe that most people have an understanding of high-speed rail, with the increasing progress of high-speed rail technology, the journey time is getting shorter and shorter, and there are more and more stations that can be reached.

Previously, the topic of "Shanghai to Beijing only takes 2.5 hours" rushed to the top of the hot search list on Weibo, the Beijing-Shanghai high-speed railway from Beijing South Railway Station to Shanghai Hongqiao Station, with a total length of 1318 kilometers, the current Fuxing train, the maximum speed is 350 kilometers per hour, if the speed of 400 kilometers per hour is realized, the running time between the two places is expected to be reduced to less than 4 hours, but with the current high-speed rail technology under development, the high-speed rail between Beijing and Shanghai can not be reached in 2.5 hours.

At the beginning of this year, the Fuxing intelligent EMU G852 train departing from Wuhan Station lasted 9 hours and 5 minutes and entered the terminal Xining Station, which is the first direct Fuxing intelligent EMU train from central China to the Qinghai-Tibet Plateau, and it is also the first time that the Fuxing intelligent EMU has driven on the Qinghai-Tibet Plateau. The moment the door opens, you can enjoy the infinite scenery of the Qinghai-Tibet Plateau.
Every opening and closing of the high-speed rail door will lead us on the journey to the destination, and the high-speed rail has created China's speed and brought China's "arbitrary door".
In addition, other props in Doraemon have also been realized, for example, the delivery phone is not the current online shopping + express delivery?indoor travel machine may be holographic photography technology, AR and VR can also achieve the same effect; the badge showing the whereabouts is like a mobile phone, it has long been integrated into our lives, through the Beidou satellite navigation system to locate the mobile phone we carry, you can know where we are. This is a banner of China's self-built and independently operated engineering and technology projects!
Science and technology are changing with each passing day, many high-tech props that only exist in comics and animations have been gradually realized and integrated into our lives, the author makes a happy and pure fantasy based on a single scene, and the scientific and technological inventions in the real world are more to solve the problems in multiple scenes, with the continuous development of new quality productivity, I believe that more and more high-tech props can be realized, and have a romantic reunion with childhood.
