In this futuristic setting an AI being has built an interstellar spaceship solely for itself, no humans or other life forms will be needed to maintain it or be passengers.
Because of the AI being, the ship will have some elements of design similar to a human ship, for story driven purposes but those will not actually be necessary for the ship to run.
As everything is run by the ships computer a more powerful extension of the AI being, all flight controls and ships maintenance will be controlled by the computer, using task specific worker bots to carry out physical jobs when needed.
The ship uses light sails powered by a laser or laser relays, it will have a space dedicated for storing large amounts of digital data, an area for material storage and manufacturing, this will be mostly 3d printing, and a laboratory for examining samples.
The computer will communicate to worker bots via wireless connection, the bots themselves will navigate using sensors to measure their surroundings.
My question is what standard design features of a human spaceships interior would still be necessary?
I see no need for lights, visual displays or interfaces, unless there would still be a reason for these and other features?
