For holodeck perversion, Barclay has nothing on Quark. And let’s be honest, if holodecks were a real thing, Quark’s programs wouldn’t even begin to touch the depravity you’d see.
Lots of people imagined VR as being the first step to a holodeck, but I think the actual hologram part is not the most important part of the holodeck. It’s the holodeck’s ability to convince people that it’s real.
The holodeck, as presented, uses some sort of AI to generate realistic interactions, and it can imitate the appearance and voice of a human. We currently have similar technology to that with generative AI and deep fakes. So, it’s like we have a couple of the basic components that make a holodeck work, but without the holograms themselves.
But anyways, the point is that we have just a small fraction of the capability available in a holodeck, and with just this tiny amount, people have already created perversions far beyond anything that the writers of Star Trek ever imagined.
