Instagram is making changes to allow alt text for the visually impaired. At first I thought "wow, that makes no sense" and then I realized that text is searchable in ways that pictures are not.
This initiative (powered by AI/neural networks again, by the way) has nothing to do with the visually impaired, and everything to do with making their pictures ever more searchable, every more advertisement-capable. It's another place where people can shove brand names of products they're definitely not being paid to endorse.
Will the automated/AI-powered text descriptions recognize brands? That would be awesome. Even if not, the manual variation will surely allow it!
