[MCU] what would successful Ultron look and be like?

I guess this can be looked at from 2 perspectives: Ultron being successful for the Avengers, and Ultron being successful for himself.

Tony and Bruce wanted a defense network that would stand in for the Avengers. Picture the autonomous suits piloted by Jarvis in IM3 or Friday in Spiderman Homecoming, but on a massive scale. 

There would be a benevolent AI deploying Ultron robots to areas in need via Satellite (a la Far From Home) or grounded distribution centers (seen in AoU with Tony's Iron Man Suits). This AI would presumably not want to kill all humans.


Ultron would want the same as above, but with the killing all humans. Maybe  with blackjack.
