If I could bring just one of these things into existence for the world it would definitely be the replicator, though I am not sure we have nearly enough power to supply it. Energy can become matter but it takes a fuckton of it to make a tiny amount.
But if this is about personal usage then I’m going with the holodeck. I’m not really hurting for material things. But manufacture any experience I want? I’ll take that.
