Comment: Ignorant and bigoted people who cannot accept China can equal and surpass Western technology always resort to the tired old mantra of "they stole it".  Just as in the sporting world, whenever a non-Western athlete defeats a Western athlete in a sport they're used to dominating, the tired and jealous refrain is "they cheated".

German engineers used to laugh at Japanese engineers - until Lexus started taking market share from Mercedes and BMWs.

Keep laughing - you will be left behind.
