Nanomachines
"Not everyone believes that molecular assemblers will be viable"
That is a bit of an understatement. Personally, I will side with the guy who has a Nobel Prize in chemistry:

These nano-scare tactics are getting old. Remove every use of the prefix "nano" and this article still has the same relevance; it just isn't as sexy. The fact is that medical diagnostics are getting better. The information available in 10-15 years is going to raise more than a few issues. The idea that this is somehow the result of "nanotechnology" is misleading. "Nano" is just a buzzword used by scientists to get funding. Vilify it and they will simply stop using the term, but that won't change the underlying science.
