What's the international position on this? I am living/working in the UK startup scene and it seems to me Berlin could become europe early stage garage very soon. Personally i believe London might be still the place to be after P/M Fit (the place to be in europe…) What's the US take on this ? Do people actually care outside of the german speaking areas and maybe Uk?
Learning German, if you're a native English speaker, is easy. Simple sentences in German can often sound like an oddly accented English. German is highly consistent, i.e. not a lot of exceptions to grammatical rules. You just have to get used to word order being different in some instances, e.g. verbs can appear at the end of sentence, and case endings. (Case endings are no big deal. Getting them wrong doesn't prevent the person listening from understanding you. Getting them right is the difference between a great speaker and a good one.) My experience in Germany around 1989 was that native Germans were more than happy to switch to English when I was stumped about how to say something in German. Learning the German language should not be a barrier.
For anyone thinking far enough ahead about being a parent, situating in Germany has other benefits. Germany has a better health care system and better public education. They are large costs/worries for any parent.
