    RIP Walter Koenig, Ensign Chekov, original Star Trek

    I'm curious about the second photo. Many of the crew members depicted, including "Chekov", don't look like actual characters I remember from Star Trek TOS, leading me to guess that the image is just AI slop. Yet a couple of different free AI detectors classify it as likely a "real" photo. So...
