"Note: I’ve seen some online chatter about the possibility that the footage shared in this post could be AI generated. Which is pretty depressing, but here we are I suppose. I just wanted to clarify that it is not. It would be pretty daft of me to be knowingly posting AI generated footage on a blog that I’ve worked hard to keep on the up and up. The footage was captured by a CBS news team, and they followed up with an interview of Atari employee (I’ll share that at a later date). Same goes for the images – they’ve been around for a while but clearly were taken at around the same time. The footage was upscaled a little on export from the editing software I used to clip irrelevant parts from. Hope this clarifies – enjoy!"
