> There's simply no option for digital sovereignty other than cultivating a strong domestic software industry.
Yes, but they tried and can't.
Those ideas of domestic computer industry and digital sovereignty have been around since the 60s.
The French had Bull which is now Atos and they failed miserably.
France was very impressive after WW2, they build almost on their own a nuclear weapons, a nuclear energy, aeronautic, military industry and impressive space capabilities.
After that you would expect them to have built a serious competitor to Intel and Microsoft but they didn't. They can't even built basic digital capabilities to support a bureaucracy.
My guess is a very different generation arrived in the 60s-70s in the workplace and in charge: the Silent Generation and the Boomers.
Those generations were not about building anything but more about entitlements and collecting dividends. But of course it takes quite some time for things to get really bad. Information technologies slowly took over many aspects over our societies over the last 50 years and now they find out they do not have sovereignty anymore.
