I imagine because they wanted humanity to be human, not machines. There are certainly arguments in favor of transhumanism for an extreme situation like this. But there is no sign that they considered it. I wonder if their attitude was that they were fighting to preserve humanity, and turning into machines is not preserving humanity. Recall that most surviving people were not exactly firing on all thrusters at the time.
Well, if the only alternative is the possible extinction of the human race... Why should you care? You can't stop the evolution. after all: by creation of PICA and VR-enviroment for human copies they already started process.
If anything, this may be a more logical "second arrow" for the Federation if lyonheart is right about the covering fleet for Langhorne being the last one of its size. You don't need nearly as many resources to preserve 80 million electronically stored mind copies as you do 80 million flesh and blood human beings.
You may not even need a covering fleet. Just one warship covering another ship carrying everything needed to Von Neumann themselves back up to a full scale civilization. Assuming you don't just send a ship off into the trackless interstellar void at STL speeds for a few centuries to wait out any Gbaba search patterns.
And even if this is too extreme - why not just "save" a copy of the entire human race on the molecular disk and send them away on the PICA-ships? After finding the earthlike planet, PICA would made necessary preparations, and then - just clone the body of every human from Earth and upload their consciousness on the data module, attached to the brain?
