Generative models have been used in healthcare for a while for things like drug design and data generation. Not to mention all the algorithms (and probably ML) used in generating results for MRI and CT scans. I don't think this is that crazy provided they can prove it's effective.
You can't be serious about conflating a host of technologies with fucking image generation or all things. This is the worst HN comment I've seen in months and there's been loads of competition.
