All this nice opensource code still is executed on hardware owned (Intellectual Property/IP) by AMD/Intel/Qualcomm/NVIDIA/Apple. Having nice European-Open Source projects is not enough without the hardware layer and standards (instruction sets, drivers), which are owned IP by US cooperation’s.

Also one needs to consider cooperation between military-complex/secret-service and big-tech cooperation, which are basically hidden subsidies for the civilian part of the business. And if eu governments do not subsidize their own tech standards similarly they will get out-competed naturally.

I guess the advantage here is that this is a single C file. This means you can run it fairly easily on an old system without a rust-toolchain or go-toolchain available.
