Building an independent web browsers. It's technically feasible and could cost 50-70 millions per year. In comparison, the national space agency costs 7-8 billions and the European union planned 300 millions in digital architecture over the next years.

The Europe rely currently heavily on US technologies, even Firefox is in the US.

Servo is an example of web browser built with 5 engineers, funded by a small company and individual donations.

The core challenge isn’t technical; it’s institutional. It can work though: CERN, European Space Agency, the Internet Engineering Task Force.

Success here would demonstrate that democratic societies can coordinate effectively on complex technical infrastructure and pass the first hurdle. Failure would reveal institutional gaps that need addressing before attempting more ambitious digital sovereignty goals.
