Could you build this?
No Steel is a GPU-accelerated rigid-body physics solver that outperforms PhysX on throughput. Building it requires novel solver algorithms, CUDA or WebGPU kernel optimization, and benchmarking expertise.
What it would actually take: A real version needs a constraint solver for rigid-body dynamics, collision detection, and GPU kernels tuned for batched simulation, integrated with a robotics framework such as Newton or Isaac Lab. It requires physics-engine and GPU performance engineers with research-level knowledge.
