The first dexterous and sentient hand prosthesis has been successfully implanted

I'm a bit uneasy about the fact that they are punching through skin. This always bears a big risk of infections as the skin is the #1 protection from bacteria. Even prosthetics fully under the skin have this risk, and septic shock is a possibly lethal threat. And we humans love to put our hands to various sometimes more, sometimes less, dirty places.

How appropriate is the term "sentient" here, given that the hand is still controlled by the brain of the human it is attached to?

The video ( <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=6WQiJPexEDM" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=6WQiJPexEDM</a> ) provides a bit clearer explanation of what&#x27;s going on. They&#x27;re actually sending signals directly through the percutaneous bone anchors, which is pretty rad in my book. Looks like the hand just snaps on to the anchors and you&#x27;re ready to go, albeit with years of retraining the nerve endings for the new signals.

On track to &quot;Deus ex: human revolution&quot; in 2027. Human prosthetics augmentation is a centerpiece of the story: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=7oTSX_csbQY" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=7oTSX_csbQY</a> .

&quot;In a pioneering surgery, titanium implants were placed in the two forearm bones (radius and ulnar), from which electrodes to nerves and muscle were extended to extract signals to control a robotic hand and to provide tactile sensations.&quot;<p>This seems pretty significant. And, I hate to sound gross but doesn&#x27;t that technically mean a prosthesis could be attached as an extra instead of a replacement?

I hope I live to see the day I can read a news article about black market cybernetic chop shops.

What if i dont need a prothesis replacement arm, but i <i></i><i>want</i><i></i> and additional third or fourth arm wearable in the form of a “backpack with arms”<p>How can i get one, and how expensive (medically and financially) will my additional sets of arms be?

Is there no video of it use?

Very ambitious use of the word &quot;sentient&quot;.... hubris much?
