Summary: Although the AdS/CFT correspondence is rigorous only for an infinite \(N\to\infty\) stack of D3-branes, it can be fruitfully studied for finite \(N\) as a source of gauge structures and choices for chiral fermions and complex scalars which solve the hierarchy problem by a conformal fixed point. We emphasize orbifolds \(\text{AdS}_5\times S^5/ \Gamma\) where the resulting GFT has \({\mathcal N}=0\) supersymmetry. The fact that the complex scalars are prescribed by the construction limits the possible spontaneous symmetry breaking. Both Abelian and non-Abelian \(\Gamma\) are illustrated by simple examples. An accurate \(\sin^2\theta\) in electroweak unification can be obtained, suggesting that this approach merits further study.
