While GPU accelerated 3D interfaces (like it in 3D games) is a good idea (at least one could mix data visualization and with controls - the way WebGL guys do it) a terminal emulator does not require any acceleration, leave alone having a Nvidia drivers or Cuda as a dependency.
What a decent terminal emulator should have is standard compliance and decent font rendering (and freetype is good-enough).
Lousy engineering will lead to lousy code, especially when the main objective is to show off (engineering is, obviously, not an objective.) Btw, using Rust is not an engineering.
Everything that can be GPU-accelerated should be GPU-accelerated. The GPU is far more energy efficient, and every bit of offload onto the GPU leads to a decrease in CPU consumption. Terminals can be particularly CPU-heavy when running a chatty program.
