Siri and Alexa make us more rude?

Will the way of issuing commands to digital assistants like Siri (Apple), Alexa (Amazon) and Google Assistant become less polite? After all, when using digital assistants, people don’t need to say polite words like “please” and “thank you”. As this issue has received increasing public attention, two researchers at the Brigham Young University in the United States decided to find out. “Hey Siri, how do we talk to you to make people less polite?” Of course, the researchers didn’t ask Siri.

Instead, they investigated and observed 274 people. The good news is that artificial intelligence digital assistants have not made adults more rude, which is unexpected.

Researcher James Gaskin, associate professor, believes that this may be because the existing digital assistant is not enough to be anthropomorphic. As artificial intelligence becomes more anthropomorphic in form, such as having expressive eyes, heads and arms that move like real people… the impact on human interaction will increase because people are more likely to think robots too Have and understand emotions.

In addition, the researchers believe that if the study is repeated for children, different results will occur, because adults usually have formed their own behavioral habits, and children’s life model has not been finalized. Parents’ concerns have prompted Google and Amazon to make adjustments to their digital assistants, and now they have added a feature: when people politely make requests, the AI ​​will also thank and praise you.

Air pollution is an invisible killer and the most important environmental factor for health problems. According to the World Health Organization report, the number of deaths due to air pollution is as high as 7 million a year. The air pollution situation in the city is particularly serious. Eighty percent of the citizens breathe unqualified air every day.

Expected to be 2050. Air pollution from cities will account for two-thirds of the global total. Therefore, improving urban air quality is imminent. What methods do we use most to improve urban air quality? Yes, it is to plant a lot of trees. Thousands of leaves can capture and absorb harmful particles from the air. However, the space in the city is getting more and more crowded, and it is getting harder to find trees in the open space.

Is there any other way? Have! A company in Berlin, Germany, invented the “city tree” to clean up contaminated particles in the air. Such “urban trees” can now be seen on the streets of Germany, such as Berlin in Germany, Oslo in Norway, Paris in France, Brussels in Belgium, and Amsterdam in the Netherlands. It is a tree, but it has nothing to do with the tree. It is a moss wall that can be moved. The wall is about 4 meters high, 3 meters wide and 2 meters thick. You can also choose to install the bench.

There is an electronic display on the wall to announce messages or advertise. This huge moss wall removes dust particles, carbon dioxide, nitrogen and ozone from the air. According to the inventor of the “City Tree”, a moss wall can absorb 250 grams of particulate matter per day and absorb 240 tons of carbon dioxide a year, which is equivalent to the absorption of 275 trees. The key is that it can also produce oxygen. “Urban Tree” does not need to be watered often like a garden. It has its own irrigation system: solar panels and reservoirs are installed on the walls.

If it rains, the rainwater will be stored in the reservoir, and then the pump will put the water Into the soil where the moss grows. In order to monitor the growth of moss, many sensors are installed in the “city tree” to upload the soil moisture, temperature and water quality to the data center in real time. In addition to sensors that monitor the growth of moss, pollution sensors are installed in the City Tree.

Help monitor the city’s air quality and the working conditions of the “city tree”. The “city tree” is simple, easy to install, and low cost, and is a very good environmentally friendly product. I hope that more and more moss walls will appear on the streets around the world. I hope that such moss walls will be “planted” into high-rise buildings in the future to improve the quality of life of urban people from inside and outside.
