After Dolly was cloned China enacted stricter ethical guidelines for researchers. Then they didn’t clone anymore. I can imagine the same happening in advance now with other ethically challenging topics around this.

And they are probably still working with bacteria or similar, but that makes for less impressive of a headline.

Edit: right, and in polo you can use cloned horses nowadays. It’s kind of a rich people thing. Possible also that that makes it more of a quiet topic, because the rich like to stick to each other.
