Prime Minister Dr Mahathir Mohamad today expressed his disappointment that people nowadays spend more money and time for research on inventing weapons than other useful needs.<br /><br />"Today, I am sad to say that every single new discovery is on how to kill people. We see the explosives being used for all kinds of weapons in order to kill people.<br /><br />"The microchip (for example) is just a collection of transistors that is very much plagiarized. If it is not for the good of humanity, I don't think it should be used in our knowledge and our power to do those things (killing people)," he said during the question-and-answer session after his keynote address at the Perdana Leadership CEO Forum 2019 in Kuala Lumpur.
