You might think writing 10,000 articles per day would be impossible. But not for a Swede named Sverker Johansson. He created a computer program that has written a total of 2.7 million articles, making Johansson the most prolific author, by far, on the "internet's encyclopedia." His contributions account for 8.5 percent of the articles on Wikipedia, the Wall Street Journal reports. 

But how can a bot write so many articles, and do it coherently? As Johansson--a science teacher with degrees in linguistics, civil engineering, economics and particle physics--explained to the WSJ, the bot scrapes information from various trusted sources, and then cobbles that material together, typically into a very short entry, or "stub."
