Despite sovereignty concerns, European firms find it impractical to switch from US "hyperscalers" like Microsoft or Google. The providers' integrated services, scale, and network effects (where customers and partners use the same systems) create a powerful lock-in that outweighs the desire for European alternatives.

Despite stated goals to build a strong domestic AI industry, governments like the UK procure the vast majority of their AI services from foreign companies. This sends a negative signal about local technology and fails to create an internal market, starving homegrown AI companies of crucial revenue.

While Britain excels in quantum research and software, its progress is hindered by a critical weakness: a lack of domestic infrastructure for specialized hardware. The country remains overly reliant on foreign providers for essential components like ultra-cold refrigerators and quantum chip packaging, creating a significant strategic vulnerability.

The new form of corporate power is not merely extracting user data for profit. Companies like Amazon, Microsoft, and Palantir now build, own, and maintain the core information infrastructures for healthcare, education, and national security, entangling public authority with corporate control and blurring lines of accountability.

While recognizing AI as a decisive geopolitical tool, Europe lacks a competitive, pan-European large language model (LLM) akin to OpenAI or Anthropic. This forces reliance on US technology, creating a strategic dependency in a critical area for future defense and sovereignty.

A significant concern fueling Europe's push for tech sovereignty is the fear that America could use its tech dominance as a weapon, shutting off essential digital services during a political dispute. This "kill switch" narrative serves as a powerful political framing device to highlight the risks of dependency.

The intense controversy surrounding Palantir in the UK is disproportionately driven by its political identity, controversial leadership, and past use cases. While technical concerns like vendor lock-in exist, other tech giants create similar dependencies for the government without the same level of public backlash.

Despite its talent, Europe struggles to scale domestic tech companies, leaving it strategically vulnerable. It's forced to depend on US cloud providers it views with suspicion or Chinese alternatives it also distrusts, with no viable third option.

The push for sovereign AI clouds extends beyond data privacy. The core geopolitical driver is a fear of becoming a "net importer of intelligence." Nations view domestic AI production as critical infrastructure, akin to energy or water, to avoid dependency on the US or China, similar to how the Middle East controls oil.
