Why do many scientists dismiss MNT as science fiction?
The whole concept of molecular nanotechnology is so complex and unfamiliar, and so staggering in its implications, that some scientists, engineers, and other pundits have flatly declared it to be impossible. The debate is further confused by science-fictional hype and media misconceptions. It should be noted that none of those who dismiss MNT are experts in the field. They may work in chemistry, biotechnology, or other nanoscale sciences or technologies, but are not sufficiently familiar with MNT theory to critique it meaningfully. Many of the objections, including those of chemist Richard Smalley, do not address the actual published proposals for MNT. The rest are unfounded and incorrect assertions, contradicted by detailed calculations based on the relevant physical laws.
