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

i tried the chaos preview in 4.23 it wasnt really a preview at all but more of a half broken somewhat implemented system. it was also different from the one the dude used in the presentation found on youtube. kinda tragic its like the apex destruction feature back in 2012 i was so hyped then started to figure out i had to stitch together dll files from different sites that wasnt documented just to get it working. if you wanna see my destruction game im making its cryosoldier on youtube username silverskateboarder. i assume we’re gonna be waiting quite some time until chaos works but i hope im wrong and i hope it doesnt crash like it does in the 4.23 branch that took 4 hours to compile.
