I hear you. We'll have to see. Times will change. Society will be different. At the moment a lot of people wouldn't do it. In 20 years, who knows. For those who don't, they might change their mind after they become aware day after day that they are experiencing pain, often a lot of pain, and those in synthetic bodies are soaring the Universe in blissful peace & harmony in amazing bodies only experiencing the amount of pain that they allow. A lot of bodily functions are handled by the subconscious mind such as pain, but as we evolve the conscious mind with its critical thinking skills will handle more, and the ASI mind will be perfectly capable of handling everything.

The way I see it is that the synthetic body is part of evolution. The next step. We're evolving. Some might say from carbon to silicon base. We're on the verge of a major change.
