Just days after a disastrous earnings report cut its stock in half, Peloton is expanding its hardware and subscription businesses, unveiling a $500 set-top-box with a camera that helps users with strength training. Known as the Peloton Guide, the device lets users access a library of strength training videos from their TV, while using a camera and artificial intelligence to correct people's form and posture, compared to the instructor. Fitness fanatics can use the $495 Peloton Guide with their own equipment, weights and accessories, which could be a problem for people who don't already own equipment. Shares dropped nearly 50 percent last week after the company lost $376 million on $805.2 million in revenue in its fiscal third-quarter, citing slowdowns in its hardware and subscription businesses.

I never should have started watching Westworld. Not because I didn't think it'd be good. An HBO show based on a Michael Crichton idea starring Evan Rachel Wood with all kinds of artificial intelligence? The problem wasn't that Westworld wouldn't be enjoyable, it was that it's the kind of show that invites obsession. The kind that presents Big Questions--that never get answered.
