Except they didn't exactly make a paralyzed monkey walk, did they? They simply paralyzed a monkey.

There are parts of this study that seem quite legit (another poster referred to them above).

However, the paralysis, surgery, and replay of data into the nervous system, just to be the first to "claim" they made a monkey walk was not one of them.

I already mentioned software is very different to biology, my issue is with reckless experimentation that has caused a lot of harm to a creature and provides no real gain. What were they actually hoping to achieve with this part of the experiment? It's already well understood that we can interface with nervous system, this is nothing new.

P.S. concern for the well being of other creatures isn't a particularly high horse. It's called empathy.
