Chinese gamers are using a Steam wallpaper app to get porn past the censors
If you have been on Steam, the world’s largest PC gaming platform, you might have noticed an anomaly on the chart of the top 20 most popular apps: Wallpaper Engine. The software lets you download animated and interactive wallpapers for your machine’s monitor.
So why does this seemingly obscure wallpaper app rank alongside global blockbuster franchises like Counter-Strike or Dota?
The epiphany will come when you begin to read Wallpaper Engine’s reviews. More than 200,000 of them are written in Chinese. And these reviews almost all talk about one thing: porn. Or more specifically, about using the software as a cloud drive and a video player for exchanging adult-only content.
Online porn is banned in China, so people there have to get creative to access it. Steam is one of the only popular global platforms still available in the country, and its community features, international high-speed servers, and increasingly hands-off approach when it comes to sexual content have made it an inevitable choice. Chinese users now make up at least 40% of Wallpaper Engine’s global user base, MIT Technology Review estimates.
However, they’re afraid they may soon lose this rare community, either because of platform content moderation or the possibility that China might block Steam altogether. Read the full story.

The big story
The therapists using AI to make therapy better
December 2021
Therapy can have mixed results, but at its best, it can be utterly transformative. What’s crucial is delivering the right words at the right time—and that can be fiendishly difficult to figure out. Several tech start-ups are determined to try anyway, using natural-language processing to identify which parts of a conversation between therapist and client—which types of utterance and exchange—seem to be most effective at treating different disorders.
The aim is to give therapists better insight into what they do, helping experienced therapists maintain a high standard of care and helping trainees improve. Amid a global shortfall in care, an automated form of quality control could be essential in helping clinics meet demand.
And ultimately, the approach may reveal exactly how psychotherapy works in the first place, something that clinicians and researchers are still largely in the dark about. Read the full story.
