Yeah.... Prosthetic companies spend lots of money on marketing to make people think we've advanced a lot further than we have.

Myoelectric limbs have been around for decades, and though the terminal devices have gotten more life-like, it's arguable if they've gotten any more functional.

Myoelectric limbs are just exhausting to use for more than a couple minutes at a time. You have to concentrate and flex individual muscle groups in your forearm to get a controlled response.

I have patients with mechanical upper limb prosthetics that are a lot more functional than I've ever seen anyone with a powered limb.
