@batman242: So how exactly is hacking the bat computer more impressive than hacking ultron?
Ultron was hacking everything in the movie, having hacked Jarvis in the beginning, then avengers tower, than hacked all governments and had access to nuclear codes, and hacked the iron legion? Hacking the entire avengers database alone was as impressive as hacking the bat computer.
Ultron was everywhere. He was all over the internet, and vision wiped him off completely.
Also were overlooking the fact that vision is a living being and has never shown any vulnerability to hacking himself.
