What of the nation state?

Well this guy seemed to think one day we might have to do it anyway

[Centurion1]

With a single unified government technological advances would peter out evebtually. The reason western europe has been so syccesfull is because of its nations close proximity and the multitude of regions. When thre is one almighty power the desire to compete and improve dissappears

[gaelic cowboy]

Hence we would have to order our society differently and seeing as there would be a world government in place this process would have started or be in place. If your running the world then you need to allocate resources responsibly the innovation comes by using education and technology to improve our use of resources to prevent collapse of the system. It is too simple to say innovation will disappear because we do not fear being attacked anymore there will still be lots of problems which need fixing even then
