Depending on which sci Fi world I think technology Manipulation would be the most versatile and broken since if it's something like techno magic like a TV that brings fictional characters to the real world or ricks Phoenix program to achieve multiversal immortality I think I would do pretty well in most situations. Especially through technology Manipulation I can control the media and techno organic beings .
Technology manipulation so I can mess with people, I'll also call my power magic just to further mess with people. Although I won't mess with everyone just people who tick me off
