Avengers: Age Of Ultron - 10 Plotholes That Almost Ruin It

10. Why Doesn't Ultron Control Any Enemy Tech?

So, Ultron's first scene ends with him escaping the Avengers (having pilfered Loki's sceptre) by jumping into their wifi connection and surfing the internet to Baron Von Strucker's base in Sokovia (which handily still has the internet turned on, obviously).

It's fairly well established that he can use this means of transportation to "infect" tech, as he does at Avengers tower to build himself a body out of spare parts, as well as in the Sokovian base. So why doesn't he ever think about doing the same thing to disable the Avengers' own tech?

Rather than letting them use their high-tech vehicles and systems (which he left in perfect working order despite wiping all of their research) to come and find him and thwart his plans, he just left them unmolested. Which includes the Hulkbuster suit: a walking armoury attached to the Internet (via Tony's Iron Man suit - he Googles "Hulk" at one point in flight).

Surely if Ultron's plan was to have Hulk rampage so much that he'd be blasted off into space or something, then incapacitating the security measure built to limit any "episodes" should have been first on his To Do List.
