I an open letter (PDF) a range of institutions call upon their respective European governments to create ELLIS, the European Lab for Learning and Intelligent Systems. It’s an effort to fortify against brain drain, and instead attract top talent to Europe. It points to the currently weak position in AI of Europe between what is happening in the USA and in China, adding a geo-political dimension. The letter calls not so much for an institution with a large headcount, but for commitment to long term funding to attract and keep the right people. These are similar reasons that led to the founding of CERN, now a global center for physics (and a key driver of things like open access to research and open research data), and more recently the European Molecular Biology Laboratory.
At the core the signatories see France and Germany as most likely to act to start this intra-governmental initiative. It seems this nicely builds upon the announcement by French president Macron late March to invest heavily in AI, and keep / attract the right people for it. He too definitely sees the European dimension to this, even puts European and enlightenment values at the core of it, although he acted within his primary scope of agency, France itself.
