With compare to relativity, the quantum mechanics is dual to relativity, i.e. by strictly outer perspective driven, as it always describes the energy wave spreading and space-time deforms from perspective of observer, which stays outside such deforms and it has some reference wave/frame available (i.e. it's Lorentz symmetry violation based). While the classical mechanics still enables us to describe for example the surface wave spreading both from perspective of surface wave (i.e. from relativistic perspective), both from light or sound wave perspective (the quantum mechanics approach). So we can consider the classical physics as a conceptual environment, which enables us to seamlessly reconcile the quantum mechanics and relativity by unique way with respect to correspondence principle without introduction of interpretation bias on background. And this is rather strong point of Aether concept - it can seamlessly connect the relativity and quantum mechanics on all ends of both energetic, both dimensional scales.
From the above follows, the contemporary view of classical mechanics as a special cases of both relativity, both quantum mechanics is fundamentally incorrect, as the exactly the opposite is true here: both relativity, both quantum mechanics are special, biased view of chaotic particle system, as described by classical mechanics, instead.
