What is the state of the UE4 physics engine in 2018 and where is it headed in the future (Apeiron)?

Order from Chaos - Destruction in UE4 | GDC 2019 | Unreal Engine

Well with the Chaos GDC 2019 video just dropped, that was interesting.

Right off the bat,

Chaos is Unreal Engine’s new, forthcoming physics system.
Chaos will replace PhysX
A preview will be available in 4.23.
It is awesome at destruction.

Purely my speculation here, but my thoughts are we probably won’t see an upgrade to PhysX 4.0 anytime soon.

Keen to have a look at Chaos in 4.23 though.
