"Bitcoin mining - the process in which a bitcoin is awarded to a computer that solves a complex series of algorithms - is a deeply energy-intensive process. "Mining" bitcoin involves solving complex math problems in order to create new bitcoins. Miners are rewarded in bitcoin. Earlier in bitcoin's relatively short history - the currency was created in 2009 - one could mine bitcoin on an average computer. But the way bitcoin mining has been set up by its creator (or creators - no one really knows for sure who created it) is that there is a finite number of bitcoins that can be mined: 21m. The more bitcoin that is mined, the harder the algorithms that must be solved to get a bitcoin become."

"Growth, then, is the animating ideal behind the platforms these companies build, and 'persuasive technology' is the means of achieving this. The research this technology is built on draws on everything from dopamine studies to behavioural psychology and addiction analysis. Features galore have emerged to keep our attention, from the endless scroll to dark patterns, but one is more important than all others, according to Fisher: recommendation algorithms."

"Their tools analyze content using sophisticated algorithms, picking up on subtle signals to distinguish the images made with computers from the ones produced by human photographers and artists. But some tech leaders and misinformation experts have expressed concern that advances in A.I. will always stay a step ahead of the tools. To assess the effectiveness of current A.I.-detection technology, The New York Times tested five new services using more than 100 synthetic images and real photos. The results show that the services are advancing rapidly, but at times fall short."

"Can AI ever be unbiased? As AI systems become more integrated into our daily lives, it's crucial that we understand the complexities of bias and how it impacts these technologies. From chatbots to hiring algorithms, the potential for AI to perpetuate and even amplify existing biases is a genuine concern. "

"The brochure also advertised "Optional Demographic Profiling Facial analysis algorithms", including "gender, race/ethnicity, age" profiling. A second, Italian-based, company was also cited on Hikvision's website as offering racial profiling. The company removed both claims from its website following an inquiry from the Guardian, and said the technology had never been sold in the UK. The document, it said, detailed the "potential application of our cameras, with technology built independently by FaiceTech and other partners"."

The ensuing controversy has sparked renewed debates about the ways in which algorithms can perpetuate biases, yielding unintended and often offensive results.

"Amazon's algorithms encourage customers pay more than they need to for popular products and appear to give more prominence to items that benefit the retail giant, according to an investigation by ProPublica. The investigation looked at 250 frequently purchased products over several weeks to see which ones were chosen to appear in the highly-prized "buy box" that pops up first as a suggested purchase. "

"Not everything is so straightforward in Google land, as Google's chat protocols Hangouts and Talk, suffered a privacy issue on the 26 September that saw instant messages routed to unintended recipients."

"Having a site that is friendly to mobile browsers on smartphones and tablets will be key from Tuesday as Google rolls out a new mobile-focused algorithm. The update to the way Google ranks search results will take into account how mobile-friendly a website is. This means companies without a good mobile website will suffer, as searchers on mobile will see sites with good mobile experiences ranked higher than those with no mobile or poor mobile sites."

"With all the information together, they created a prediction model which can guess with 80% accuracy whether or not that user will go on to be banned from just their first five posts. "

"Facebook announced late Friday that it had eliminated jobs in its trending module, the part of its news division where staff curated popular news for Facebook users. Over the weekend, the fully automated Facebook trending module pushed out a false story about Fox News host Megyn Kelly, a controversial piece about a comedian's four-letter word attack on rightwing pundit Ann Coulter"

"Facebook is mired in a series of controversies about the curation of its news feed, from its broadcasting live killings, to editing out an iconic photo of the Vietnam war, to accusations of political bias. It recently tried to smooth the process out by firing its human editors … only to find the news feed degenerated into a mass of fake and controversial news stories."

""Personalised, preventative healthcare is mission critical to the future-fit healthcare service we want to build," said Hancock last week. "We must harness the latest technology and techniques to move away from the one-size-fits-all approach of the past."" - DO YOU AGREE?

"Luddism refuses to die because each innovation creates a pool of people who feel economically or culturally dispossessed. The greater the leap forward, the wider the chasm of obsolescence. And the scale of the digital revolution defies hyperbole. No area of human activity is undisrupted. "

"Vast sums are being spent by governments across the industrialized and developing worlds on automating poverty and in the process, turning the needs of vulnerable citizens into numbers, replacing the judgment of human caseworkers with the cold, bloodless decision-making of machines. "

"The greatest propaganda machine in history. Think about it. Facebook, YouTube and Google, Twitter and others - they reach billions of people. The algorithms these platforms depend on deliberately amplify the type of content that keeps users engaged - stories that appeal to our baser instincts and that trigger outrage and fear. It's why YouTube recommended videos by the conspiracist Alex Jones billions of times. It's why fake news outperforms real news, because studies show that lies spread faster than truth. And it's no surprise that the greatest propaganda machine in history has spread the oldest conspiracy theory in history - the lie that Jews are somehow dangerous. As one headline put it, "Just Think What Goebbels Could Have Done with Facebook.""

"acebook has come under fire this week after a hoax story about women being abducted in white vans went viral on its platform. The site's algorithms are thought to have perpetuated the circulation of the story."

"The Cyberspace Administration of China (CAC) unveiled a 30-point draft proposal for "algorithm recommendation management regulations" that would directly affect companies including ByteDance, Tencent Holdings and Kuaishou Technology. The rules would forbid practices that "encourage addiction or high consumption", as well as any activities that endanger national security or disrupt social and economic order."

"Among other things, the declaration states that military AI needs to be developed according to international laws, that nations should be transparent about the principles underlying their technology, and that high standards are implemented for verifying the performance of AI systems. It also says that humans alone should make decisions around the use of nuclear weapons."
