You remember Dolly the sheep? Who had old-age issues when she was young, thus raising concerns about the utility of cloning? Well, it turns out there are several sister clones from that exact batch of cells who aren’t having any trouble at all.
How about that? Of course it doesn’t much matter to SF writers. If you want clones, put ’em in your book. That’s far more realistic than wormholes or whatever. But in the real world, well, very interesting! I have no desire to see any society base itself around azi labor (say). On the other hand, I have no problem with the idea of cloning in general. As far as I’m concerned, a clone is just a twin of a different age. Speaking as a twin, I find that concept profoundly non-disturbing.
Anyway, I was just interested to see this update on Dolly and her “sisters.”
