Mecha fighting has evolved to modern times and has basically reached its operational limits!
Just like the 100-meter sprint in human sports, whether it's the starting technique, mid-race acceleration, or the final sprint, thousands of years of research have developed these skills to near perfection.
Even the best athletes can hardly make any substantial improvements in this area.
The top 100-meter runners can only perfect these techniques and defeat those who are less perfect.
The same goes for Mecha.
The ultra-sensitive universal control stick and the virtual keyboard that responds at will are the basic components of Mecha commands. Combined with the Mechanical Computer that auto-recognizes commands and corrects operational errors, it truly integrates humans and Mecha together.
Practice has proven this to be the safest and most stable mode of Mecha control.
