But views vary: some believe investors should hold their funds; but many have also sounded the alarm on bitcoin while expressing doubts on other cryptocurrencies.” According to Coindesk That’s what Wall Street says. But “Silicon Valley is extremely bullish,” on , citing the rise of initial coin offerings — or ICOs — as one of the many factors currently fueling the ascent of bitcoin. writes Nick Bilton VANITY FAIR “In typical Valley fantasy, people are seeing only the positive potential with bitcoin, not the potentially ugly outcomes when humans molest it for their own interests,” he says.

SOCIAL MEDIA ALGORITHMS : “2017 was the year we fell out of love with algorithms.” WIRED titles Fake news, Russia’s interference in the US election, hate and extremism online… Those are all phenomenons that have spun out of social media algorithms abuses. Interesting fact: The Collins English Dictionary named “fake news” as 2017, winning over another related word that made the shortlist, “echo chamber.” Word of the Year WIRED cites Congressman , ranking member of the US House Intelligence Committee. Last month, in a hearing about Russian interference in the 2016 election, he threw this accusation at Facebook’s top lawyer Colin Stretch: “Part of what made the Russia social media campaign successful is that they understood algorithms you use that tend to accentuate content that is either fear-based or anger-based.” Adam Schiff Even , director of ’s and former advisor to president Barack Obama, addressed the phenomenon in an interview with : “Everything is pushing us toward algorithm-guided, customized offerings. That’s true in politics and in journalism. That worries me.” David Axelrod UChicago UChicago Politics Nieman Lab “Letting algorithms become bogeymen can also blind us to the reason they are so ubiquitous,” WIRED writes. “They are the only way to make sense of the blizzard of data the computing era blinds us with. Algorithms provide an elegant and efficient way to get things done — even to make the world a better place.” Is that so? “Using algorithms to analyze our metadata can personalize everything from our searches on Google to the products we’re recommended on Amazon to the news stories Facebook thinks we’ll be interested in,” . “But personalization isn’t always good. The so-called ‘filter bubble’ effect can mean we get stuck in online echo chambers, never presented with news that conflicts with our own world view.” Digital Trends explains 5. UNICORNS Looking at the Collins English Dictionary shortlist for 2017, in addition to “fake news” and “echo chamber,” another tech-related word made the list, “unicorn.” Word of the Year By the way: the word “Insta” also made the list. Collins defines it as: “(1) an imaginary creature depicted as a white horse with one long spiralled horn growing from its forehead, regarded as symbol of innocence and purity (2) a recently launched business enterprise that is valued at more than one billion dollars.” Obviously, the latter applies to my list of most talked-about in tech in 2017. , which cites data, 57 startups became unicorns this year, the third-busiest year for companies reaching $1 billion valuation, and seven lost their horns. According to Recode PitchBook 6. CYBERSECURITY PitchBook, which I mentioned in my previews entry, that “Cybersecurity — or, in many cases, the lack of it — has made its fair share of headlines this year, from the Uber data breach that cost the ridehailing company’s chief security officer his job to the WannaCry ransomware attack.” explains Not only cybersecurity has made headlines throughout the year, but investors and VCs have shown a lot of interest in the sector with the highest amount of capital of the past decade invested in the industry. “So far in 2017, VC investors have invested about $4.2 billion in cybersecurity startups, eclipsing the previous high reached in 2015,” per PitchBook’s data. Two companies, and , are also unicorns with valuations over $1 billion. Rubrik, Inc. Illumio 7. AI Artificial intelligence — or AI — and machine learning are everywhere. Literally! They are in our smartphones, in our homes, in our car. They power our social media experience, our Alexas and Google Assistants, our personal banking, and nearly every other part of modern life. Virtually every big tech company is pouring funds into AI. Academia is publishing papers and research. of The Verge: “Artificial intelligence boomed this year like few other areas in tech, but despite the scientific breakthroughs, glut of funding, and new products rolling out to consumers, the field has problems that can’t be ignored. Some of these, like company-driven hype and sensationalist headlines, need better communication from the media and experts. Others challenges are more nuanced and will take longer to address, such as bias in algorithms and the growing threat of tech firms becoming AI monopolies as they hoover up data and talent.” According to James Vincent Experts compare AI to electricity because it’s a resource with the potential to transform a broad range of industries.

Even governments are taking “high-profile steps towards advancing AI over the past two years,” as the . “These range from prospective research about the potential impacts of AI to large amounts of funding and ambitious strategic plans to bolster national capacity to take advantage of the technology.” Center for DataInnovation explains Via on Twitter.
