Today, most scientists, including Drexler himself, believe that a 'gray-goo' scenario is highly unlikely.
'So-called gray goo could only be the product of a deliberate and difficult engineering process, not an accident. Our technology is not advanced enough to create such tiny, independent nanorobots.' says Chris Phoenix, Director of Research at the Center for Responsible Nanotechnology' (CRN)
'Our technology is not advanced enough to create such tiny, independent nanorobots.' he adds.
