well yes, that was Arthur C Clarkes thought experiment wasn't it?It is not limited to science fiction. If you could bring a modern computer (or similar devices) to the world of 1800 or earlier, you could easily convince the people that it is magic. Don't forget a power supply if the device does not run with batteries.
But I don't really mean that sort of things.
More like the processes humans reserve to gods: creation of life forms, habitats etc.
