Both of these artificial intelligences are pretty smart and they have a lot of influence in technology. That being said, Viki’s a super computer that has a lot of memory on her side. Tycho (UESC) is also impressive, but he doesn’t seem like he would last against her. Viki’s dominant personality would essentially vanquish Tycho’s as she would take over his systems. In a battle of A.I. there can only be one winner! Viki wins.
