Very interesting. I'm currently trading off whether to use Mojo or C++/pybind to accelerate simulations that combine matrix operations with fine-grained scalar calculations. I only recently learned that pybind + cppimport offers the integrated compile-on-import experience available in Mojo.
Mojo makes SIMD and GPU programming more ergonomic than what you would obtain from C++, I imagine this should factor into your decision process. The language is just less mature overall.
