Who programmed these defenses?

1 Transporter costs : 600 food, 1500 lumber and 350 iron.
1 Defensive Trebuchet costs : 600 food, 8000 stone.
The game's AI wasted TEN Defensive Trebuchets to kill a single Transporter, nevermind that even if there were no wall fortifications the one lone transporter would die after 100 rounds for failing to breach the wall. Nevermind that there are 1500 perfectly good archers towers that can kill the 1 transporter without using up anything. Programmers, please buy more brains?
