And: conservatism isn't bad per se. For many people it means a kind of safety and familarity. Maybe for most folks, it's more important to have a good dayjob that supports their families, than to follow the "arrogant academic" into unkown waters...
I think as the article points out the problem is more of the rigid and hierarchical business culture of Germany.
Also Germans are much less international. The dutch and nordics are much much more tuned into the anglo-saxon world were the majority of software innovation happens.
That is a function of being small countries who always had to look outwards and learn other languages and cultures. Germans seem far more insular to me.
If you look at the German Mittelstand, you can find 1000+ small and medium enterprises who have world wide business from rural areas.
This is the typical german mindset. You better be avarage, following the german mediocrity.
