Power Corrupts. Warp Power Warps.

Holodeck technology allows so many incredible things that wouldn't be possible in the real world. You can try out risky medical procedures, teach new recruits with bridge simulations, pull up battle scenarios and take various tactics and work through them systematically to come up with the best approach. The possibilities are endless.

And yet, there's basically one thing humans are going to use that technology for once we get it. You know it, and I know it. And although we may now have altruistic aspirations and erudite ends in mind, more often than not in real life the holodeck technology would be used for a little thing we like to call Gettin' It On. *cue Barry White*
