Moar got started because Rakudo hates Parrot. Rakudo already had a code to embed Perl in Rakudo on Parrot. That was called Blizkost or something. I guess they threw away that code too. The other AM is right. This is a project that can't finish anything.
When trying to reach for the moon, sometimes you end up at the top of a tree. Well, then if you want to go on, first you have to climb down from that tree.
As I understand it, Parrot appeared to be poorly designed. It is very much useful, since it allowed rakudo to run and developers learnt a lot thanks to it, but it will probably not go much further.
Implementing Perl 6 is no easy task. No wonder it is not a straight road.
As I understand it, Parrot appeared to be poorly designed.
Parts of it aren't right now, but that's for two reasons. One, the design of P6 has changed several times since 2001. Parrot always had the unenviable task of trying to provide a stable platform on which to build P6 and other languages (especially Perl 5, which was a goal for a long time) while trying to adapt to changes made to P6. Two, Rakudo developers actively opposed changes to Parrot, even those designed to improve the architecture of Parrot for Rakudo. (See Re^8: MoarVM update or #parrotsketch of 06 September 2011.)

Now that all of its developers have been driven off, you're probably right.
