If you follow (even if loosely) the APNIC blog, you've surely came across Geoff Huston's articles. ✍️
I strongly recommend this episode from APNIC's PING podcast where Geoff explains BGP RPKI, and ends up almost making the case *against* it (and IPv6 too).
Given he usually covers both topics in a very positive way, I found it awesome how this time he makes you look at these problems from another angle.
