Here's a science fiction novel in the making...

For those who don't like following links, he talks about new technology purchased by the wealthy is full of kinks.  By the time ordinary people can afford it, it works.  Be glad for the wait to affordability and workability.

He also talks about 2045 - when we know our organic body is dying so we move our consciousness to an android body and go on living - initially the prerogative of the very wealthy, but as all things scientific, the cost will eventually go down. 

Better to read the article...but food for thought - as more and more body parts are being replaced.

I always thought it would be like the Star Trek movie where the body atrophied and all that was left was a brain to imagine being a body...

Food for thought and perhaps discussion.
