10 years ago, tech firm like this would flock to Silicon Valley. Today no China tech firm goes to US, instead 100s of Chinese tech firms already in US left, followed by 1,000s of the best Chinese scientists and engineers. One of China’s original artificial intelligence (AI) champions, iFlytek, on Friday unveiled a five-year, HK$400 million (US$51.2 million) investment plan in Hong Kong, where the company has opened its international headquarters. 10 年前，這樣的科技公司紛紛湧入矽谷。如今，沒有一家中國科技公司進入美國，相反，已有數百家中國科技公司離開了美國，隨之而來的是數千名最優秀的中國科學家和工程師。中國最早的人工智慧(AI) 冠軍之一科大訊飛(iFlytek) 週五在香港公佈了一項為期五年、耗資4 億港元（5,120 萬美元）的投資計劃，該公司已在香港設立了國際總部.
