The Download: listening robots, and Google’s AI emissions

This is today's edition ofThe Download,our weekday newsletter that provides a daily dose of what's going on in the world of technology.

A way to let robots learn by listening will make them more useful

Most AI-powered robots today use cameras to understand their surroundings and learn new tasks, but it's becoming easier to train robots with sound too, helping them adapt to tasks and environments where visibility is limited.

Though sight is important, for some of our daily tasks, sound is actually more helpful, like listening to onions sizzling on the stove to see if the pan is at the right temperature. Training robots with audio has only been done in highly controlled lab settings, however, and the techniques have lagged behind other fast robot-teaching methods.

Researchers at the Robotics and Embodied AI Lab at Stanford University set out to change that. They first built a system for collecting audio data, then used this data to train robotic arms how to execute the task on their own. The team's new training algorithms help robots gather clues from audio signals to perform more effectively. Read the full story.

The big story

Social media is polluting society. Moderation alone won't fix the problem

August 2022

We all want to be able to speak our minds online-to be heard by our friends and talk (back) to our opponents. At the same time, we don't want to be exposed to unpleasant speech.

Technology companies address this conundrum by setting standards for free speech, a practice protected under federal law, hiring in-house moderators to examine individual pieces of content and removing them if posts violate predefined rules.

The approach clearly has problems: harassment, misinformation about topics like public health, and false descriptions of legitimate elections run rampant. But even if content moderation were implemented perfectly, it would still miss a whole host of issues. We need a new strategy: treat social media companies as potential polluters of the social fabric, and directly measure and mitigate the effects their choices have on us. Read the full story.
