An advantage of no exhibits, is that the building has no security guards beyond the front desk. There are no ropes, no warnings not to touch the exhibits. They would rather you touch them. In fact, there are several horizontal touch screen surfaces scattered throughout the museum, functioning as both tables and as interactive display surfaces, able to call up information on a whim, and access the central databases. Some can even affect the displays on the walls around them, changing those to meet inputted data.
The basic hope is to pull as many visitors as possible, away from touring the ruins (and taking bits of it), and instead tour the increasingly interactive and immersive museum experience.
