AdS == Anti de Sitter space == A universe with nothing in it.

These physicists assume a universe with nothing in it, then populate it with physicists and quantum computers and wormholes.

This is like claiming to have the most beatiful differential equations that explain perfectly the weather on earth. You say "ok, let's test these beautiful equations." But it turns out that the equations so beautiful to look at have no perfect solutions. So you need to make absurdly symmetrical assumptions to arrive at a usable solution, like assuming no atmosphere. Then, with no atmosphere your equations explains the earth's atmosphere perfectly well. With beautiful mathematical gimmicks, of course. With an assumption of a universe with nothing in it your equations explain everything in that universe with nothing in it.

Physics is neo-scholasticism powered by the marketing skills of the practitioners. This episode about wormholes proves the corruption of academic physics.

Newtonian space == a universe with nothing in it, which is then populated with fictitious continuous rigid bodies. Yet we use it to build bridges.

Physics is about models. Some are useful. AdS/CFT is useful. I know this because I spent the time to study it in grad school, rather than dismiss it out of hand.
