I have personally accepted only 2 options exist.
One is that machines or bio engineering advancement puts humans on an equal level with mutants initially and then with time makes them superior to mutants as shown by life 6.Moira cannot avoid this eventuality so I guess she is trying to unite mutants to race ahead in the species race with immortality and carefully crafting omegas (Legion and Proteus) among other omegas who are not allied to Krakoa explicitly.
There is one huge factor missing in her calculus,she thinks by going back in time she has a headstart,when in fact it is Humanity that already has a headstart because the Children of the Vault are absolutely homo novissima and they are not only darn powerful but have branched away from humanity and do not consider themselves human ,they are the 3rd species
Which is why I think Synch,X23 and Darwin were sent into the vault by Xavier to have mutants inside there to help a) steal technological evolution secrets mutants don't have for example on accelerated evolution(though Elixir and Tempo seem to know a thing or two,maybe just not to the level of CoV) and b) have a few mutants evolve as homo superior novissima to still be able to fight for the mutant cause if life 6 became reality again.
One huge flaw in her and mutant thinking is that Homo superior novissima in her mind will still tow the line yet we know already CoV don't tow any human line,they want humans and mutants exterminated.So how Moira hopes 3 mutants after being in the vault between 537 years(issue of Jan) and 1880 years (if the story of that expedition is taken up now) still have the mutant cause at heart is anyone's guess.She seems to assume even in dilated time their powers and cognitive prosess will be the same.What makes Xavier and Moira think that I don't know- at a bare minimum they evolve beyond being mutant or have more in common with CoV than mutants realise.They can see that evolution through the vault is more effective than Keakoa because they don't need death and resurrection to incrementally become better versions of themselves but just let accelerated time do the evolution.
My point is they may not like humanity or mutants any more than CoV after reaping that technological boost in evolution.Moira and co may have just accelerated mutant and human demise. It's up to the writers to write but I see it more logical that the three will cast their lot with CoV than with humanity or Krakoa
Which brings me to the second option,the only real way out of this is locking humans and mutants in a vault like in Ecuador to all evolve as one species Homos novissima(superior or not)
