Personal dream: in-your-attic IC factory. Along the lines of what people like Jeri Ellsworth or Sam Zeloof have been doing. But cheap-ish (and hopefully, small) enough that almost anyone could have one. Or even more generic: some device to assemble atom-sized structures to your liking. Like what has been demonstrated with scanning tunneling microscopes: pick up an atom here, deposit over there. Quick enough to produce, say a ~1M+ transistor IC in a week or so. That would be like a 3D printer on steroids. Or a chemical variety: have a few mg. of life-saving medicine produced in your attic. That could do away with the power of Big Pharma overnight. Unlike say, faster-than-light travel, none of these things conflict with (known) laws of nature; it's technology, miniturization & software for the most part.
