I am curious to hear what HN thinks of calling these things robots. These are frog embryos that have been surgically reshaped and had muscle cells implanted in them.
While this is amazing technology and there will no doubt be useful applications for such devices (for lack of a better word) in various fields, do we really need to play with fire and make them self-replicating?
It's necessary for it in the first place, given that they placed evolutionary constraints on it for it to work.
