So do the programs in the SINK, but they are actually just very well programmed personality programs.
Are you talking about the vendor or the whole thing?
Not sure about the vendor but I know the rest of the programs are actually self aware, you can asking the SINK vendor if they are AI and he will explain it.
And the suit is pre-programmed to read vital signs and inject Med-X and Stimpacks when it thinks its appropriate.
It got me addicted to Med-X on my Legion character who only took chems to sell them.
Glad I sold it for about 7,000 caps (the suit not the Med-X).
