Also remember that in Star Trek the most ubiquitous technology was the pin-on-walkie-talkie, during use of which people would look up at the ceiling. It was a show defined by the 80's/90's, with several plotlines that could have been resolved by someone having an iPhone in their pocket, or by the Enterprise having smart drones. There were only a couple of episodes that dealt with holodeck addiction, and just one or two in which the holodeck was used to its full potential: as a reconfigurable-on-the-fly work space that can tie into ship-systems, and either show or replicate any hardware or display you describe verbally. If the holodeck were a real thing, I would rarely come out of there. I'd just make real friends inside other holodecks, and we'd spend our lives learning and creating stuff. It would be an enormous social problem. 60's StarTrek tech doesn't count. Although Kirk's stylus/pad for signatures is not unlike the UPS guy's… and I'll bet Uhura's metallic ear slab was bluetooth.
