In honararium of Arthur C. Clarke, best known '2001 - A Space Odyessy' but also a scientist. Not a biotech guy, but his laws are gerneral enough that they apply.
1. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
2. The only way of discovering the limits of the possible is to venture a little way past them into the impossible
3. Any sufficiently advanced technology is indistinguishable from magic.
