That doesn't really contradict their premise about making modern RTS. StarCraft and Age of Empires 2 are ancient at this point. An entire generation of kids has grown up since they came out.
I don't think the fact that you could make a successful mainstream RTS way back then really says much about whether you could make one in 2024.
I read the article but I'm still confused how this works.
My understanding is the herpes virus DNA is integrated into our own. So once the gene editing molecules snip at the herpes virus damaging it, how does the chromosome get put back together?
Is it actually sniping at two places in the herpes genome in a way that the two ends match up and reform while cutting out a section in the middle?
