The first genuinely honest ad for generative AI I've ever seen, from Microsoft / CoPilot A mediocre white guy sees his non-white colleague getting praised for good work, he asks AI to *literally copy it*, and then he gets all the praise instead: www.ispot.tv/ad/SoDi/micr...

Seeing so many gleeful posts on LinkedIn saying things like: oh we're using .NET so we wouldn't have stupid vulnerabilities like this, come talk to us about moving your website to a different platform. Absolutely ridiculous: something like this can happen to any software project.
