A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.

Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

I don't know about that. It seemed to have a pretty rapid impact on the phone in that video, and it's not like those are exactly open. And they weren't pressurizing it.

Helium is tiny, and will diffuse though pretty much anything other than continuous welded metal pipe very very quickly. The elastomer seals on a phone would slow it down slightly, but the article's from 2018, before so many phones were watertight. I remember my old iPhone had a little piezo cooling fan in one of the grates on the bottom, so helium would have no trouble at all.
