My problem is that she wasn't even mentioned. Surely Carter would be much more helpful than Jeannie. They could of mention she was doing something else, and was busy administrating. There is no way Carter in all these years hasn't done coding. Everything (not everything but a lot of the advance tech stuff) is based on coding.
On the other hand The Seer did establish that Carter did not have a place in this project (busy doing other things) nor had the expertise on this kind of replicator coding. At least she would have at good grasp of what McKay is talking about. Honestly I grieve every time she is deprived of jumping in and helping out with the science/tech stuff. Wasted talents/experience. But after all these years Carter deserves to lead something big like Atlantis, and it makes sense.
