It’s exciting to imagine how future humans will have solved the problems we have now, or what amazing new inventions will mar lives more convenient and interesting. We asked top scientists to share their predictions on what the world will be like in a century. If they’re right, the 2114 is going to be really cool.
1. Robots will do your chores and more
Robots will be doing most of our jobs, from building homes to teaching math. There are already robots that clean floors and pump gas. In the future they will be more complicated and useful. Unfortunately, with robots taking all the jobs, unemployment will be high.
2. You will read minds.
Speaking of being social, we will communicate in an entirely different way. Forget texts and emails. Mind-reading technology will allow us to send thoughts to each other without speaking a word. We will also be able to send thoughts to objects around us. (Instead of pressing “start”on the microwave, you could just think “start.”) Meanwhile, chips implanted（植入)in our brains will improve memory and intelligence.
3. Your car will drive you
Today, around 30,000 Americans die in car accidents each year. One hundred years from now, accidents will be a thing of the past. According to Mark Safford, consultant or the U.S. Department of Transportation, future cars will drive themselves. These electric cars will communicate with other cars on the road to travel safely in close formation at high speeds.
4. You will eat fake meat.
Raising animals is not an efficient way to produce food, and it harms the environment: Cows, chickens, and pigs eat a lot, and then we have to deal with all that poop（粪便). What’s more, that poop can rise up poisoning lakes, rivers, and streams. Today, scientists can “grow”meat in a lab from animal cells, but it’s expensive and not very delicious. In the future, they will have perfected the process. You’ll order hamburgers that come from factories, not cows. Scientists may even find ways to make lab-grown meat tastier and healthier than the real thing.

The USA is a land of immigrants. Between 1815 and 1914, the world saw the great peaceful migration in its history: 35 million people, mostly Europeans, left their homelands to start new lives in America. Why did these people risk everything by leaving their homes and families?
First, one major cause of the departure among European peasants was the rise in population which in turn led to hunger. Another was politics. Many young men fled eastern Europe to avoid being forced to join the army.
Physical hunger provided another pressing reason. Following the failure of the economy of southern Italy in the 1860s, hundreds of thousands decided to make a new
