Depending on who you ask, blockchains are either the most important technological innovation since the internet or a solution looking for a problem. The original blockchain is the decentralized ledger behind the digital currency bitcoin. The ledger consists of linked batches of transactions known as blocks (hence the term blockchain), and an identical copy is stored on each of the roughly 200,000 computers that make up the bitcoin network.

In May of 2017, nearly a year after Gawker shut down, a story mysteriously disappeared from its archives. The 2015 article detailed leaked emails written by Sony Pictures CEO Michael Lynton, which had become public after the company’s servers were breached in 2014. The story was removed as the result of an undisclosed lawsuit—and served as a troubling reminder that journalism on the internet is fragile, and subject to censorship by wealthy and well-connected individuals.

Not long after Uber’s pugnacious founders first tested their app among San Franciscans, a pair of Harvard Business School classmates from Malaysia seized upon a similar idea: They wanted to build Uber, but for Asia. In 2012, they launched a ride-sharing service with 40 drivers in Kuala Lumpur. Eventually, they settled on the name Grab. Six years later, Grab dominates the ridesharing market in Southeast Asia, boasting 2.3 million drivers in 168 cities across eight countries.

So you still have no idea how to talk about cryptocurrencies at a cocktail party. That's fine: Your livelihood doesn't depend on it. But for a certain segment of the population—investors, industry analysts, lawyers, really anyone who's tech-adjacent for a living—it's suddenly their job to have something "smart" to say.

For the past few years, Facebook’s quarterly earnings calls have been something of a victory lap. Even at its massive scale---$40 billion in annual revenue and more than half of the world’s internet users, the company manages to grow consistently each quarter, even beating analyst expectations. Wall Street has rewarded the company with a stock price that can only go up, increasing 560 percent in five years and placing Facebook among the most valuable companies in the country.

Artificial intelligence is overhyped—there, we said it. It’s also incredibly important. Superintelligent algorithms aren’t about to take all the jobs or wipe out humanity. But software has gotten significantly smarter of late. It’s why you can talk to your friends as an animated poop on the iPhone X using Apple’s Animoji, or ask your smart speaker to order more paper towels.

In the first issue of WIRED, published 25 years ago this year, founding editor Louis Rossetto declared that “in the age of information overload, THE ULTIMATE LUXURY IS MEANING AND CONTEXT.” (Caps his.) If anything, that simple observation rings even truer today. That’s why WIRED has always valued depth. We dig deep into our subjects, reveling in wonky engineering details that other publications skip. We think deep thoughts about the future.

Virgil Griffith discovered the allure of hacking in 1993, while slumped at an Intel 80386 system in Tuscaloosa, Alabama. He was 10, and he was on a losing streak at Star Wars: X-Wing. To hit the leader­board, he’d need a fleet of ace wingmen, but he only had one X-Wing fighter that could hold its own in the game’s World War I–style dogfights. Desperate times call for desperate measures.

The interstate highway system wasn't built in the name of convenience or even commerce. When President Dwight D. Eisenhower signed the Federal Aid Highway Act of 1956, he did it in the name of national security. In fact, the official name of the system is the Dwight D. Eisenhower National System of Interstate and Defense Highways. Now some in the Trump administration are arguing that the federal government should build a broadband wireless network for much the same reason.

A coalition of 97 child health advocates sent a letter to Mark Zuckerberg on Tuesday asking him to discontinue Messenger Kids, a new advertising-free Facebook app targeted at 6-to-12-year olds. Advocates say the app likely will undermine healthy childhood development for preschool and elementary-school-aged kids by increasing the amount of time they spend with digital devices.
