Max More, CEO of the cryonics company Alcor, has produced a video in response to physicist Michio Kaku's surprisingly weak critique of cryonics.
In all fairness to Kaku, he kinda had this coming.
First, he couldn't even get the terminology right, describing the practice as "cryogenics." As More points out in the video, that's the branch of physics addressing the production and effects of very low temperatures. Cryonics, on the other hand, is the act of storing tissue at low temperatures in the hopes of eventual reanimation.
Kaku also describes cryonics as something only millionaires can afford (not true), he completely fails to account for the application of cryoprotectants (though he perplexingly talks about it as theory), and makes the claim that cryonics companies are fooling people by promising them immortality (also not true). Watch Alcor's response to these claims:
Here's Kaku's original Big Think video:
