The US intelligence chief James Clapper was the first to warn in February 2016, in a report declassified by the CIA, about the risks of CRISPR Cas9 technology and classified it in the category of potential “weapons of mass destruction”. For him, this technology used in thousands of laboratories should be considered as equally dangerous as the North Korean nuclear program or Syrian chemical weapons and Russian cruise missiles. So, about the modification of genomes, shouldn’t we fear of creating an additional example of the use of high-risk human intelligence, such as nuclear energy? Rather than achieving technology to eliminate a large proportion of serious illnesses, doesn’t man take the risk of developing even more serious and even less curable diseases?
