William Andregg ushers me into the cluttered workshop of his startup Fathom Computing and gently lifts the lid from a bulky black box. Inside, green light glows faintly from a collection of lenses, brackets, and cables that resemble an exploded telescope. It’s a prototype computer that processes data using light, not electricity, and it’s learning to recognize handwritten digits. In other experiments the device learned to generate sentences in text.

Special Counsel Robert Mueller released a bombshell indictment Friday, implicating 13 Russian nationals and detailing a multi-year, costly, and widespread effort to influence the 2016 presidential election.

Angel Torres was driving down a major Los Angeles boulevard in late 2016 when it happened: Ride requests from Uber and Lyft arrived at the same second. As he looked away from the road to decide which trip was more worth his time, he nearly rear-ended the car ahead of him. “It scared the crap out of me,” Torres says.

Do not let their names fool you. The silicon places---Silicon Slopes, Silicon Prairie, Silicon Beach, Silicon Peach, Silicon Bayou, Silicon Shire, Silicon Desert, Silicon Holler, Silicon Hill and, separately, Silicon Hills---do not aspire to become “the next Silicon Valley.” Sure, the country’s burgeoning tech enclaves in Utah and Kentucky and Oregon draw inspiration from the original.

In the twilight of the 20th century, Bill Gates was well and truly a tentacular squid, with his sucker-covered limbs extending into every level of the computer industry.
