Can you elaborate on what he meant by 'imitation gene'?
People who engage in standard trendy forms of "nonconformity" that everyone immediately recognizes as "nonconformist" are called "dangerous" or "edgy" or "innovative". People who lack the imitation gene are called "weird" or "crazy".
That's probably not exactly the way Peter Thiel would phrase it - I'm uncomfortable speaking for others - but I don't think he'd disagree.
