Doubt it. Lack of professional attitude. Disastrous politicians. 3rd tier universities. Lack of capital. Large underclass, big welfare spending.
It is very hard to set up a "silicon valley". The silicon valley had and has some very unique points, including military origins, if I remember right. Germany still has a strong and broad industry, which is lacking in most Eastern and Western European Economies. This is an advantage (try to do a non-software technology start-up in a country that does not have the suppliers and partners, then you know). In the end it is extremely unlikely that EUrope will achieve something similar than the Silicon valley.
Yes, Berlin once was a scientific, cultural, industrial and technological powerhouse. These times won't come back.
The more interesting question would be, can China manage to create a new silicon valley? I have my doubts.
