ONE doesn't disappoint.
Let me see if I got things right:
Bofoi and Child Emperor work together to build an AI.
They eventually abandon the project.
Kuseno steals this incomplete AI and uses it to make Drive Knight.
All the other evil robots are based on Drive Knight.
Bofoi eventually completed the original AI on his own. (as mentioned last chapter, though he said it would still need to be trained)
Which means we might still get to see the completed-AI in action this arc. Or perhaps something tragic will happen to Genos, and this AI will be the solution for him to regain his peace.
I imagine that even if Kuseno's whereabout are finally revealed, it won't just be easy to storm in and get him. And since he's supposedly so evil and intelligent, the barriers won't just be firepower, because we already got the moment of Saitama trivializing the supposed boss of the arc.
