    Taxi e-payment rules / OpenAI's Pentagon deal / Gen Z emotional distress survey / Combatting rising obesity

    On this programme, we started things off with a closer look at an upcoming regulation that made the availability of electronic payments mandatory for all taxis. From April 1st, all taxi drivers in Hong Kong will be required to offer at least one QR-code-based and one non-QR-code electronic payment method.
    We then heard from our tech correspondent about OpenAI’s controversial deal with the Pentagon to use its models for US defense systems. The US military had blacklisted OpenAI’s rival Anthropic, deeming it a “security risk”. The move came after Anthropic refused to cross ethical boundaries, including using AI tools for the purpose of fully autonomous weapons without human oversight.
    After the break, we chatted with a representative from the Mental Health Association about a recent survey by the organisation which found that over 40 percent of Gen Z in the city had been affected by emotional distress.
    And lastly, we heard from a senior health official about a new government initiative that aimed to combat rising obesity rates in Hong Kong.

    On Friday's Backchat, we looked at the International Conference on Roads and Railways 2025, which is co-organised by the Highways Department and the Hong Kong Institution of Highways and Transportation. The theme of the event is “Building Smart and Green Transport Infrastructure”, and we spoke to an expert about Hong Kong's transport infrastructure blueprint beyond 2030.

    We then heard from the organisers of the Hong Kong Streetathon about what runners can look forward to this November.

    After the break, we learned more about Hong Kong’s inaugural Digital Education Week that will begin later this month.

    Wrapping up the show, we heard from an expert about a symposium that explored the transformative power of stem cell science in healthcare and biotechnology.
