The most important step we are missing is the first one, where we "easily" edit the genomes of humans. It is not yet easy, despite the enormous hype surrounding CRISPR-based approaches. Edit: and I understand that gene drive could make it easier to introduce biallelic changes, but this isn't really easy because the drive systems themselves are not even 10% efficient at introducing the exact modification which is desired.
