HPC is a special industry in that regard. HPC is know to take well managed technical risks such as building custom CPUs (A64FX in Fugaku) or using less popular architectures (SPARC, Power). If one can be certain that with enough coding hours codes can be adapted to run on those platforms and they will end up faster more exotic hardware will be bought or considered. Nation level HPC projects are not conservative, Industrial HPC maybe a bit more so.
