These datacenters planned by SAP, Telekom etc. appear to focus on AI datacenters, not general digital sovereignty. I think LLM training is much, much less important than getting governments, companies and individuals away from american tech giants.
Also, who will get most of the money? NVIDIA, an american company. Buying 500k american GPUs for billions isn't the grandiose step towards sovereignty they make it out to be.
Why not invest the money in EU chip design? Why not EU hardware design and manufacturing? Why not industrial automation and robotics? Installing renewables, improving infrastructure? There are other challenges which are more likely to be useful than power-hungry slop machines. I have yet to see LLMs being used for non-trivial tasks reliably. The most frequent use for LLMs I have seen is to relieve people from thinking critically or putting in the effort to learn skills properly. Which are both extremely bad and dangerous things that will actually reduce productivity and quality in the long term.
