  @hodlbod and @jb55 were talking about this on a recent Thank God for Nostr podcast. 

My takeaway was that it's very good but has serious scaling limits because of this.  
 I'm fine with the scaling limits, I just don't want my rectum inverted everytime I write "Gm" 
 😆 A reasonable request. 
 GM

OH GOD. WHY DOES MT RECTUM FEEL THIS WAY?! 
 Why should your GM be private??? Share it with the world!!

 I don't know firsthand, but I believe they encrypt each message for the recipient, hence the scaling issues. They've been working on adopting MLS for 3 years, which will help a lot when it gets done. 
 encrypted group messages are an unsolved problem as soon as the group becomes too large afaik 
 That's what MLS is for, it reduces the amount of messages needed from O(n) to O(log(n)). Which is nice, but still doesn't scale as well as O(1) which is what you get with shared keys (at the expense of much worse security). 
 the most important thing is that Matrix does not encrypt metadata 
 Matrix can be run Sovereignly. This helps as you are in full control of who you add into the rooms. Also, you can customize the server where no emails are used. It goes without saying don't dox yourself with a username. Also, if you federated with only other sovereign runners of their Matrix instance your attack vector is highly minimizesd. 
 It's ok for government, enterprise, etc., but not for casual users.

 It will scale better when they finish integrating MLS (they've been working on it for 3 years, with the help of the German government).
