TenForward: Where Every Vulcan Knows Your Name

Yes, Voyager's writers take this position, but I think it's nonsense.

Holograms are programs that run on a computer. They have no physical form, they are force fields and light being projected from a piece of hardware bolted to the wall to convince you they have form, but their true "self" is just data in a computer like any other program. Their experiences are database entries. They can be deleted, copied, transmitted, paused and restarted like any other program. They are incapable of doing anything that the computer they're running on can't do.

Like the EMH miners that pass along Photons Be Free - total bullshit. Why simulate that much intelligence when you've already installed devices all over that are capable of scanning and mining ore without physical form or the capacity for misery? Just let the computer do the work.

Or the Hirogen holograms. They're simulating pain, and it's fucked up the Hirogen want it that way, but does that make it unethical to hunt them? After all, when you hurt them, you're just updating a data structure in a computer that calculated the trajectory of your phaser fire, determined it was a hit and decided to relay that information back to you as simulated damage and pain. It could just as easily make the holograms impervious to all damage.

The Doctor can be special to the crew and they can want to keep him intact and running without pretending he's more than a simulation - he's designed to create rapport and they've bonded with him. But holograms in general? You might as well be concerned about being nice to a replicator or a navigation array, or an NPC in a videogame.
