The article was tl;dr for me, but I have to note the irony of them using an AI generated image for the hero. It's a great image to go along with the content, but maybe undermines their stated concerns a little?
Very fun. AIM was a huge part of my high school existence.
I was absent from AIM for several years, but then my first job out of school (2009) used it as the official chat service. Eventually the corporate overlords brought in a series of other sanctioned chat tools, but most of us kept AIM going to have a backchannel we knew wasn't monitored.
