  We discuss certain effective improvements on superrigidity for
$SL_n(\mathbb{Z})$ for finite $n>2$. Using these ideas we then use
superrigidity to prove a representation stability theorem about pointwise
finite dimensional $VIC(\mathbb{Z})$-modules, which itself can be viewed as a
superrigidity theorem for $VIC(\mathbb{Z})$ and $GL_\infty(\mathbb{Z})$
