Are the ship computers powerful enough to run all turrets by AI Blades?

It depends what other Computer Blades you want to equip and whether you upgrade the Computer items, but as it stands, the plan is that you won't be able to completely convert all turrets to be controlled via AI using the default loadout. We presently estimate that 4 of the 6 can be converted to AI as standard without any extra item tweaks but this system is still to be implemented.
