Taxpayers are paying something like HK$200 billion for Hong Kong’s contribution to two controversial infrastructure projects, the Hong Kong-Zhuhai-Macao bridge and the Express Rail Link. Concerns have been raised about both projects and the degree to which Hong Kong has relinquished control over aspects of their construction and operation. On Tuesday last week, the last carriage of an Express Rail train was derailed during testing. Two days later, news media revealed aerial images of an artificial island that’s included in the bridge project. This appeared to show that part of it was drifting away. With me in the studio are Albert Lai of the Professional Commons & Raymond Chan, former Head of the Geotechnical Engineering Office.

Talking of things that are complicated brings us to the grilling given to Facebook founder and chairman Mark Zuckerberg by US legislators this week. Top of their agenda were questions over Facebook’s collaboration with Cambridge Analytica which harvested the data of an estimated 87 million Facebook users and used the results for political campaigns. Some people thought that Zuckerberg dodged tough questions others were struck by the level of ignorance among lawmakers about how the internet works. Zuckerberg was asked at one point whether he was willing to reveal which hotel he was staying at while in Washington DC. He was not. The point being that information of this kind can easily be obtained from unwary Facebook users. Meanwhile we’ll see you next week, possibly by means of Facebook - hum.
