I want to share this video with students to highlight the importance of learning computing today. Many A-level students do not realise, but their peers in universities (especially those from overseas) are mostly well-equipped with computing knowledge in pre-U. My students know that I use wolframalpha a lot to get answers for them; fyi, wolframlapha is written by the speaker of the above video.
I advise my students of mine to pick up a computing course or two, on Coursera (which is free). This will greatly aid their learning!
