"As for these mechas that require pilot operation, they were completely phased out decades ago, replaced by more advanced prosthetic technology."
Dongdong asked puzzledly, "Little prosthetics can replace such big things? In a real fight, mechas still seem more formidable, right?"
Dorne patiently explained, "In terms of absolute power, mechas are indeed very strong, but they also have huge drawbacks."
"To accomplish precise work with a mecha, ordinary mechanical operation isn't sufficient. Human central nerves must be connected to the operating system for neural synchronization between pilot and mecha."
"This method is effective, but it also poses a huge issue—the burden caused by synchronization is too heavy."
"Under neural control, pilots aren't 'operating' mechas; they are fused with them. You can think of it as an external, oversized prosthetic."
"People who can endure this way of piloting might be one in tens of millions."
