Awesome, not awesome.

"There are far more trees in the West African Sahara and Sahel than most would expect. A combination of artificial intelligence and detailed satellite imagery allowed a team from the University of Copenhagen and international collaborators to count all trees across a 1.3 million km2 area of West Africa..."This technology has enormous potential when it comes to documenting changes on a global scale and ultimately, in contributing towards global climate goals. It is a motivation for us to develop this type of beneficial artificial intelligence," says professor and co-author Christian Igel of the Department of Computer Science." Learn More from the University of Copenhagen >

"Biased human judgments can affect AI systems in two different ways. The first is bias in the data that systems learn from. You can see this play out for yourself: do a Google image search for “professional haircut,” and another for “unprofessional haircut.” “Professional haircut” turns up results that are exclusively white men, while “unprofessional haircut” has much more gender and racial diversity. (This issue was originally surfaced by Twitter users back in 2016.)" - Greg Satell and Yassmin Abdel-Magied Learn More from Harvard Business Review >
