I think Alice is overly paranoid due to being... whatever she is. I think her caution is justifiable, though, and I think her reasons for keeping Ardent away from machines are sound, but not the motives she ascribes to the Praeses. I think it more likely that the Praeses are trying very hard to reestablish some kind of contact with the surface world, and started off relations by sending what they thought would be a welcome gift: a solution to all the things the Praeses perceive as hardship.
Obviously, there is quite a disconnect between Alice and the "thinking trees", but I don't think her opinion can be relied upon, either.
