20、geuOur vision:III.D-based system SW/HW development Currently,our technology roadmaps are mainly inspired by Python,Red,D,Zig,Rust,Nim and MojoIV.Wrap-upu We do think is one of the best candidate for next generation system programming,especially in the HW/SW Co-designed Edge Computing Infrastructure which has more freedom to innovate.u has great potential,but still has a long way to goethods together with AIu u +intro will be awesome!
