It's "Computer, lights!" and we're still not close to Star Trek, because our computing is ridiculously fragmented. Instead of a unified, configurable system doing our bidding, we have a whole ecosystem of apps that try to be everything but helpful. Can you imagine captain Picard saying, "computer, tell Hue to turn on the lights", or "computer, tell Northrop Grumman® Unified Weapons Platform™ to charge Phasers™"?
Star Trek is not anymore what it used to be.
