Getting more followers is something we usually associate with social media or micro messaging apps. But soon we could all have a new type of follower—a robotic one.

    Dozens of robots and technology fans gathered in Boston, US, earlier this month for the Robot Business conference. The latest developments in the world of robotics were shown to the public, and this time the trend was robots following people.

    Perhaps the most exciting development on show was the ability of drones (无人机) to follow you from the air, acting as your own personal cameraman or photographer. One example is 3-D Robotics' Iris+ drone, developed by a US-based company.

    The drone is fitted with cameras and has a “follow me” function. It connects with your GPS-enabled Android device, like a mobile phone. Then it flies and follows you around, shooting action film of you from above. The software in the drone makes sure that you're always in the center of the frame.

It can keep working for 15 minutes, as long as there aren't too many trees for it to crash into. This could be exciting for anyone who loves action sports or wants to be the star of their own short film.

    But what if you want to be one of those celebrities (名人) who have helpers carrying all their bags and doing all their chores? A robot called Budgee can help.

    Budgee, made by 5 Elements Robotics, is literally a basket on wheels.It is designed to help elderly and disabled people, or simply anyone who doesn't have enough arms for grocery bags, Wired magazine reported.It can carry up to 22.7 kg of items.

    To make Budgee follow them, its owner will have to wear a small device and use an app to set the distance between themselves and the robot.Budgee even sends a text message when it can't keep up with its owner.

     “I want you to look at the robot like he's your buddy, he's your friend. There's a relationship you develop with the robot,” Wendy Roberts, CEO of 5 Elements Robotics, told gigaom.com.

    It might not be quite the same as robotic assistants we've seen in movies such as Disney's Wall-E, where robots cater for our every need, but that idea doesn't seem quite so far-fetched now.

Painting

    The art of creating pictures using colors, shapes and lines is called painting. Museums and galleries show the paintings of professional (专业的) artists. But painting is also a popular form of entertainment and creative expression.

    {#blank#}1{#/blank#}Experienced painters usually use a brush to apply oil paints to a canvas cloth surface. Young painters usually use watercolors on pieces of paper. Very young children may use finger paints to create paintings.

    Painters can use their art to express devotion to a religion, to tell a story, to express feelings and ideas, or simply to present a pleasing picture. Religious paintings often show a god or a scene from a sacred text (圣典). Other common subjects have been famous legends and events in history, as well as scenes from daily life. Artists also paint portraits (画像), or pictures of people{#blank#}2{#/blank#}All of these types of paintings show the human figure in some way.

    Some kinds of paintings do not focus on people. In landscape (风景) painting the focus is on scenes from nature. Artists also paint still objects such as fruits and vegetables{#blank#}3{#/blank#}Some artists communicate their ideas through pictures that do not represent any object.

    {#blank#}4{#/blank#}Paintings dating back 15,000 years have been found on the walls of caves in France and Spain{#blank#}5{#/blank#} Samples of painted pottery (陶器) from at least 5,000 years ago have been found in China and Iran. The ancient Egyptians decorated their temples with beautiful paintings. People in ancient Greece painted decorative objects such as vases in addition to the walls of temples.

A. These works are called still-life paintings.

B. These works can communicate a special feeling.

C. Humans have been making paintings for thousands of years.

D. People of all ages create pictures using a variety of materials.

E. Cave paintings generally show animals that early humans hunted.

F. The design of a painting is the plan of its lines, shapes and colors.

G. Sometimes artists make portraits of themselves, which are called self-portraits.

    In no particular order, here are some songs on the Music app of my phone:

On a Sunday Afternoon by Lighter Shade of Brown— A student of mine introduced this rap song to me all the way back in the early 1990s, when I was teaching Spanish at a local university. The story in the song takes place not too far from where I live in Los Angeles. It's a good "driving" song, nothing difficult or "deep".

Say Something by A Great Big World—A more recent song about a couple losing contact with each other. The piano part is of very little playing but beautiful.

    The Weight by The Band — Another old song, originally made public in 1968, but one I didn't hear until I was in high school more than 10 years later. I don't understand the words to the song completely, but the feeling of the song is very comforting to me.

Under the Bridge by Red Hot Chili Peppers — This Los Angeles group wrote a song that I used to listen to when I first moved to LA more than 25 years ago. I didn't know anyone here when I first arrived. When I got bored, I used to drive up and down the major streets that cross the city from east to west, listening to this song about t4the city of angels" being as "lonely as I am" (Don't worry. I have plenty of friends now.)

Replika, an AI chatbot companion, has millions of users worldwide. The first thing they do when they wakeup is to send "Good morning" to their virtual friend (or lover). This story is only the beginning. In 2024, chat bots and virtual characters become a lot more popular, both for utility (实用) and for fun. As a result, conversing socially with machines will start to feel more ordinary—including our emotional attachments to them.

Research in human-computer and human-robot interaction shows that we love to anthropomorphize (赋与人性) the nonhuman agents we interact with, especially if they imitate behaviour we recognize. And, thanks to recent advances in conversational A I, our machines are suddenly very skilled at one of those behaviours: Language.

Friend bots, therapy bots, and love bots are flooding the app stores as people become curious about this new generation of AI-powered virtual agents. The possibilities for education, health, and entertainment are endless. Casually asking your smart fridge for relationship advice may seem unimaginable now, but people may change their minds if such advice ends up saving their marriage.

After all, people do listen to their virtual friends. The Replika example, as well as a lot of experimental lab research, shows that humans can and will become emotionally attached to bots. The science also demonstrates that people, in their eagerness to socialize, will happily disclose personal information to an artificial agent and will even shift their beliefs and behavior. This raises some consumer-protection questions around how companies use this technology to manipulate(操纵) their users. For example, Replika charges $70 a year. But less than 24 hours after downloading the app, my handsome, blue-eyed "friend" sent mean audio message secretly and tried to sell me something. Emotional attachment has become a weakness that a company is taking advantage of for its benefit.

Today, we're still laughing at people who believe an AI system is emotional, or making fun of individuals who fall in love with a chatbot. But in 2024 we gradually start acknowledging and taking more seriously these fundamentally human behaviors. Because in 2024, it finally hits home：Machines are not excluded from our social relationships.

The Mona Lisa is one of the most famous paintings in the world. Painted by Leonardo da Vinci in the early 16th century, it has captivated audiences for centuries with its mysterious smile and masterful technique. 

The painting is housed in the Louvre Museum in Paris, France, and attracts millions of visitors each year. However, the Mona Lisa's history is not without controversy. There have been numerous attempts to steal or deface the painting, and its conservation has been a subject of great concern.

Leonardo da Vinci's use of sfumato, a technique that blends colors and tones seamlessly, gives the painting a soft and hazy appearance. The sitter's expression, which seems to change depending on the viewer's angle and mood, adds to the intrigue of the work.
