It depends on what we mean by “strategic autonomy”, and it depends on what we mean by “digital sovereignty”, which is an analogous frame that's getting used a lot now.
Think about, for example, the information ecosystem, where most of my work is. The fact that our information ecosystem is now largely reliant on both a small number of U.S. platforms and a small number of U.S. large language models would certainly create difficulties if these were to be leveraged and used against us. Should we be developing more autonomy in both of those respects? Yes, we should be building Canadian systems, and there are many others who can speak better than I can about the infrastructure needed to do that. We also need the ability to govern the ones we use. Right now, we have neither. We have neither our own systems nor the levers through which we can govern the foreign products we use.
I think that twin deficiency is a real vulnerability, as you point out.
