Every year has its ups and downs. The ups are a thrill. The downs are often fascinating, for what they reveal about the limits of our ambitions, the challenges of trying to get things right and the escape hatches that might get us out of trouble (or the rabbit holes that take us ever deeper).
Or just because misery loves company. At this time of year, we regularly take a look back at the craziness that unfolded in the world of technology. There were notable slipups and outbreaks of weirdness, which CNET news chief Roger Cheng has chronicled in his wrapup story; I particularly liked his use of the term “an iceberg of terrible” in describing all the trouble that accumulated around Facebook/Meta in 2021.
That story is among the many in-depth features and thought-provoking commentaries that appeared on CNET this week. So here you go. These are the stories you don’t want to miss.
