Aiko can now read documents, recognize 250 faces per second, repeat directions, and distinguish between such sensations as a light tickle and pain.

She's spunky as well. Her inventor tested her patience by fidgeting around as she tried to feed him, eventually telling him to feed himself.

Once Aiko has been perfected, Le Trung hopes to sell clones for use as home helpers. He says with enough sponsors, he can mass-produce the robot and sell it for about 500 US dollars each.
