The show said it was an AI section 31 designed for threat assessment didn't it?I see they still havnt answered the question of what control/layland is.
My thinking was they are some version of the borg that evoled from the encounters in First Contact and ENT
Which would mean the time line goes
TOS, TAS, TNG, First Contact, ENT, STD, which would mean that what happenes in ENT and STD are a new time line that is caused by the Borg and Enterprise-F going back in time with there advanced technology at that point.
The show runner (or one of the executive producers) has said they weren't thinking borg when they came up with it, and seeing how it seems to have been neutralised I'm inclined to believe her until the show tells us otherwise tbh.
What hasn't made clear is how it took over Leland or why what appeared to be a retinal scanner had a fuck off needle incorporated into it.
