Discusses classic AI history: original DeepDream used InceptionV1 as a testbed for early mechanistic interpretability, and VGG16 powered artistic style transfer. Surprisingly, VGG16 is still used for perception loss in latent diffusion autoencoder pretraining. Switching to modern dense feature extractors like DINO seems to make almost no difference.
