Uber Starts Charging What It Thinks You’re Willing to Pay
On Friday, Uber acknowledged to drivers the discrepancy between their compensation and what riders pay. The new fare system is called “route-based pricing,” and it charges customers based on what it predicts they’re willing to pay. It’s a break from the past, when Uber calculated fares using a combination of mileage, time and multipliers based on geographic demand. Daniel Graf, Uber’s head of product, said the company applies machine-learning techniques to estimate how much groups of customers are willing to shell out for a ride. Uber calculates riders’ propensity for paying a higher price for a particular route at a certain time of day. For instance, someone traveling from a wealthy neighborhood to another tony spot might be asked to pay more than another person heading to a poorer part of town, even if demand, traffic and distance are the same.

A Taxpayer-Supported Version of Facebook - The Atlantic
So, haven’t we just replaced one tech-centric explanation with another? Not quite. If the combination of online news, social media, and echo chambers led to political polarization and ideological capture, we’d expect to see the same phenomenon on the left as on the right. We don’t. In our study, people who read far-left sources like Daily Kos or Mother Jones are generally also engaged with center and center-left sources like the New York Times, The Washington Post, and CNN. The new right’s echo chamber is hermetically sealed, while the left’s is not. (Of course, if you’re within that hermetically sealed chamber, you’re likely to see CNN as just as left-leaning at The Nation.)

Artificial intelligence runs wild while humans dither
A study published last month in the research journal Plos One, analysing the use of bots on Wikipedia over a decade, found that even those designed for wholly benign purposes could spend years duelling with each other.

In one such battle, Xqbot and Darknessbot disputed 3,629 entries, undoing and correcting the other’s edits on subjects ranging from Alexander the Great to Aston Villa football club.

The authors, from the Oxford Internet Institute and the Alan Turing Institute, were surprised by the findings, concluding that we need to pay far more attention to these bot-on-bot interactions. “We know very little about the life and evolution of our digital minions.”

The Data That Turned the World Upside Down - Motherboard
a then little-known British company based in London sent out a press release: "We are thrilled that our revolutionary approach to data-driven communication has played such an integral part in President-elect Trump's extraordinary win," Alexander James Ashburner Nix was quoted as saying. Nix is British, 41 years old, and CEO of Cambridge Analytica. He is always immaculately turned out in tailor-made suits and designer glasses, with his wavy blonde hair combed back from his forehead. His company wasn't just integral to Trump's online campaign, but to the UK's Brexit campaign as well.
