Militärische KI verantwortungsvoll nutzen und Regulierung neu denken

Panel Discussion, Lecture

Künstliche Intelligenz findet im Militär immer breiteren Einsatz, von Logistik und Training über Missionsplanung und Zielidentifikation bis hin zu autonomen Waffensystemen. Gleichzeitig wächst die Bedeutung von Mikroprozessoren immer stärker, der Zugang zu seltenen Erden und Chips wird zur zentralen Ressource. KI kann das Kampfgeschehen beschleunigen und damit destabilisierend wirken. Der Wettlauf um neue Fähigkeiten birgt jedoch auch Eskalationsrisiken. Wir laden Sie ein, diese Themen im nächsten Crisis Talk gemeinsam mit unseren hochkarätigen Podiumsgästen zu diskutieren.

Das Prinzip Donald Trump und die Verrohung der Welt

Panel Discussion, Lecture

Ein neuer Politikstil macht international Karriere. Er ist gekennzeichnet von Vulgarität, Verrohung und erklärter Rechtsfeindschaft. Machtinteressen werden nicht mehr juristisch bemäntelt. Stattdessen wird das angebliche Recht des Stärkeren zur Staatsdoktrin gemacht – innenpolitisch wie außenpolitisch. Treibende Kraft hinter dieser Verrohung der politischen Sitten ist ein US-Präsident, der nicht nur die amerikanische Gesellschaft und Kultur, sondern auch die globale Ordnung nach seinen Vorstellungen und Interessen umgestaltet. Die Römerberggespräche wollen diesen Politikstil verstehen.
