There was some paper where they sticked ones head into an MRI and had them look at a photo, and they used fMRI (detect which parts of brain are most active) and with a calibrated linear transformation from brain activity to stable-diffusion weights in some layer they were able to read the subjects minds with their fMRI. In other words, once it was calibrated they could use fMRI to read minds by getting stable diffusion to draw what the subjects see, using the mapping from fMRI activity to the model weights. If that is true then it means there is some light on some parts of human intelligence.
