數字平台通過降低消費者的搜索成本,有助於知名度不高的文化工作者找到知音,讓在傳統市場乏人問津的產品能以較低成本進入市場,令市場百花齊放。然而,在「流量為王」的時代,平台運營日趨偏頗,尤其是在中國的數字文藝娛樂市場,平台的推送和操縱能決定一部作品的命運,甚至窒礙產業創新。

當今經濟結構變化極快,投資教育的開支不一定會帶來高回報,那麼上大學還值得嗎? 由於內地經濟處於調整期,大學畢業生不單難找工作,更不尋常的現像是,學歷愈高的畢業生反而愈難就業。筆者認為這種現象的主要原因是中國教育產業在過去20年擴張過度,加上經濟發展不均加劇,社會流動性減弱,抑制了教育回報。而人工智慧技術的廣泛使用,為未來的教育回報帶來更大的不確定性。
