The cost of building the perfect wave
For nearly as long as surfing has existed, surfers have been obsessed with the search for the perfect wave.
While this hunt has taken surfers from tropical coastlines to icebergs, these days that search may take place closer to home. That is, at least, the vision presented by developers and boosters in the growing industry of surf pools, spurred by advances in wave-generating technology that have finally created artificial waves surfers actually want to ride.
But there’s a problem: some of these pools are in drought-ridden areas, and face fierce local opposition. At the core of these fights is a question that’s also at the heart of the sport: What is the cost of finding, or now creating, the perfect wave—and who will have to bear it? Read the full story.

What happened when 20 comedians got AI to write their routines
AI is good at lots of things: spotting patterns in data, creating fantastical images, and condensing thousands of words into just a few paragraphs. But can it be a useful tool for writing comedy?
New research from Google DeepMind suggests that it can, but only to a very limited extent. It’s an intriguing finding that hints at the ways AI can—and cannot—assist with creative endeavors more generally. Read the full story.

Quote of the day
“It’s really easy to get people addicted to things like social media or mobile games. Learning is really hard.”
—Liz Nagler, senior director of product management at language app Duolingo, tells the Wall Street Journal it’s far trickier to get people to go back to the app every day than you might think.
The big story
The big new idea for making self-driving cars that can go anywhere
When Alex Kendall sat in a car on a small road in the British countryside and took his hands off the wheel back in 2016, it was a small step in a new direction—one that a new bunch of startups bet might be the breakthrough that makes driverless cars an everyday reality.
This was the first time that reinforcement learning—an AI technique that trains a neural network to perform a task via trial and error—had been used to teach a car to drive from scratch on a real road. It took less than 20 minutes for the car to learn to stay on the road by itself, Kendall claims.
These startups are betting that smarter, cheaper tech will let them overtake current market leaders. But is this yet more hype from an industry that’s been drinking its own Kool-Aid for years? Read the full story.
