Holographic parents?

While parents are on duty with the military, touring in Iraq, Afghanistan, or any other part of the world, would their young children benefit from talking to a hologram of mom or dad? Not a high tech version of webcams but an artificial intelligence that responds to voice cues. The child would start up the hologram like program on the computer and have simulated conversations about everyday things.

I think it's sort of freaky. Mind you, this isn't set up yet, the Pentagon is still looking for the right technology and stuff like that. However, it seems sort of strange to have a simulated parent. It seems different from recordings in a way, though I can see some similarities. But a recording or video is made by an actual person, and an AI is just a fancy computer program.
If a child is too young to understand why their parent or parents are gone, aren't they also too young to understand that the computer image they are talking to is not their parent? Isn't that sort of misleading for them? Or is that the point?

Ethical issues can be confusing and they are almost always controversial.
