I'd really like to see Google's Red Team dig into the POWER 9 CPUs to see if they are a viable, if expensive, alternative for actual security, and not just the market-speak from Talos and IBM.
      Phoronix did a comparison last August (and numerous other times) and IBM publishes information about POWER exploits on their website, it's not only the mitigations but also compiler maturity and architecture performance that determine which company has the most bang for the buck.

      AMD is planning a tweak to its architecture in Milan, and it makes sense that they would fix what they can in the hardware.
