Yes, I wrote that too, but that's with the Interface and Full Haptic . So pay your Cr7000 or 10000 per ton (cheaper if you wire it yourself), install a Ship's Brain and you can have Lucy fly the ship like it's her body.
But that's a Ship's Brain and not a Ship's Computer. The ship's computer isn't envisioned as doing that - though when it gets to TL16 and runs a Conscious Intelligence program, it likely ought to get to operate that way, but if you want to wire it to have DEX, at least pay the Cr2000 per ton. Otherwise, you get Virtual Crew. And even if you have skill 0 everywhere, you'd have to run one instance of the skill to fire each turret and, again without the haptics you don't get DM+3 at TL 15 for DEX: you're better off with one of them High Guard firing packages like Advanced Fire Control.
But that's the way I intended it, anyway. You can Rule Zero it anyway you want.
