Why the hype around medical genetics is a public enemy

Science has always issued medical promissory notes. In the 17th century, Francis Bacon promised that an understanding of the true mechanisms of disease would enable us to extend life almost indefinitely; René Descartes thought that 1,000 years sounded reasonable. But no science has been more optimistic, more based on promises, than medical genetics. Recently, I read an article promising that …
