I would create a cross-platform GPU-targeted GUI framework for .NET Core. Something like Avalonia, only without skia, directly on top of D3D11, GL, GLES or Metal. Modern GPUs are awesome, can directly render very complicated vector graphics. Outside Windows not used for GUI despite there's need for that, slow mobile CPUs + very high rez displays are both common.
