“I didn’t intentionally get infected with COVID-19 just to figure out whether Apple’s exposure notification system was working, but it ended up that my experience might offer some additional insight to the situation.” Daniel Eran Dilger’s long and discursive piece for AppleInsider on whether Apple’s COVID-19 exposure tracking is working kind of buries the lede: he got the dubious opportunity to try it out, as implemented in Germany and Switzerland. It wasn’t as flawless or as seamless as you might have hoped. “Over a week later, neither Germany nor Switzerland has used my positive test result to send warnings through the system Apple created. That’s important because the timing of exposure notifications have a very limited useful window. By the time I got a positive result, I likely wasn’t even contagious any more.”
