Imagine you are taking a plane from Tokyo to Paris, enjoying the first-class travel, a big dinner with four dishes and a city tour without leaving the ground.

This isn’t a fiction story in a movie or novel. This is the future of air travel according to Japan's First airline, which has used the power of virtual reality (虚拟现实) to create dream vacations. Passengers avoid a high cost to the airport. However, they can enjoy the first-class travel and a fantastic tour of Paris. All this can be quietly completed in Tokyo. Also, First Airline offers other virtual flights to New York, Rome and Hawaii.

It just take you 4,980 yen (日元) to choose business class. “For me, it’s difficult to have real trips because of the cost like time and money,” Hirokai Abe said. “If I can take such a flight even though it's virtual, I think it will be so cool.”

After getting on the “plane”, passengers can sit down and experience the two-hour flight. They are surrounded (环绕) by things in a real plane, which can make their tour more like a flight.

Passengers will be served with a delicious meal. The menu depends on where passengers want to go — Manhattan meat soup and cheesecake for New York and onion soup for Paris. When “arriving”, passengers can enjoy a 360-degree tour of the city.

The company tries to give people a perfect vacation, and their service is perfect for those whose ability to travel abroad is limited (限制) by the cost or health.

In many movies, there are sometimes characters who have chips（芯片）implanted（植入）in their heads.This might come true very soon.

Neuralink, US businessman Elon Musk’s company, has developed a chip that was implanted into the head of a pig. On Aug 28, Musk did a livestream（直播）on how it works by showing the signal transmission（信号传输）.

The chip is the size of a coin. It has over 3,000 electrodes（电极）that can monitor（监测）about1000 neurons（神经元）. So in the livestream while the pig was breathing, people could see its brain activity on a large screen. If this technology is used on humans, after the chip picks up signals in the brain, these signals will be sent to nearby computers or APPs and then be translated into actions, such as moving an arm or leg.

It’s not a dream for people to use a small chip to change their life with their minds. For now the goal is to use it to help disabled people. They could control artificial limbs（假肢）with their minds and move around more easily. People could even use the technology to play video games or drive cars.

However, there is still a long way to make these things happen.The chip can send signals from about 500 neurons in the pig’s brain. However, the human brain has 80 billion neurons. Also, it is not safe to implant the chip yet, it could harm the brain. Hackers（黑客）could also hack into the chip and control others thoughts and feelings. There is another problem, too. When humans are connected to computers, are they still humans?
