They use swords(sword looking plasma cutters technically?) in Star Wars, and thats one of the coolest sci-fi futures ever. So right on, cool drawing.

I do not think that they will have to use swords in the Sci-fi future they will have better weapons like minigun that shots nukes or something that can delete the whole universe in less than 1 second! yes you heard me I said 1 second there are more things that you can do in less than 1 seconds like 1 seconds rise you just put the rice in the water and its done you're rice is gone somebody has ate it? I do not know I am not the rice man
