As much as the idea of "holographic rights" might seem ridiculous from a real-world point of view, it's definitely not
a non-issue within the Trek
universe because holograms are capable of reaching sentience. And as Optimus Prime would say, "Freedom is the right of all sentient beings."
If artificial intelligences could not attain sentience, Bry, what does that say about Data? How is he any different from Voyager's EMH? The only real difference is what their bodies are made of. If humans (or Vulcans, or whatever) can create a sentient positronic life-form, why can't they create a sentient holographic lifeform?
