Warp drives are no more realistic than orcs.
*cough*Alcubierre drive*cough*
The Alcubierre metric, while a theoretically interesting speculation, is still pretty implausible, from the humongous energy requirements, to the issue of information transport, to the problem of impacting a speck of dust at superluminal speed. Compared to that, creating an orc with genetic engineering would be rather mundane.
Not so humongous anymore. Refinements to the shape of the toroid have decreased the reaction mass to generate a warp field to that ~ the size of the Pioneer spacecraft (down from a Jupiter-sized planet).

The Alcubierre drive math checks out. What we lack are metallurgy and energy production technology (at present).
