  We show that if $A$ is $\mathcal{Z}$, $\mathcal{O}_2$,
$\mathcal{O}_{\infty}$, a UHF algebra of infinite type, or the tensor product
of a UHF algebra of infinite type and $\mathcal{O}_{\infty}$, then the
conjugation action $\mathrm{Aut}(A) \curvearrowright \mathrm{Aut}(A)$ is
generically turbulent for the point-norm topology. We moreover prove that if
$A$ is either (i) a separable C*-algebra which is stable under tensoring with
$\mathcal{Z}$ or $\mathcal{K}$, or (ii) a separable ${\mathrm{II}}_1$ factor
which is McDuff or a free product of ${\mathrm{II}}_1$ factors, then the
approximately inner automorphisms of $A$ are not classifiable by countable
structures.
