I have a feeling the computing demand for every AI use case the Danish military could want to pursue, could be met by a few mainframes with fewer security risks. Given the work that goes into verifying the data center meets some assumably very high requirements, I imagine mainframes might even be the cheaper solution too. Seems to me like yet another example of companies successfully lobbying governments to buy unnecessary things.
