I had the pleasure and honor to address the Foreign Affairs Committee of the German Parliament (Auswärtiger Ausschuss des Deutschen Bundestags). The hearing focused on the technology rivalry and technical standards.
The other experts were Dr Daniel Voelsen, Andy Mueller-Maguhn, Prof Bernhard Schölkopf, Dr Ulrich Sandl and Sibylle Gabler.
The hearing was broadcasted live in German and the video is now available in high-resolution on the website of the German parliament and in smaller resultion here on this website.
