A few weeks ago, I found myself at a local café in Berlin, surrounded by buzz—an open laptop here, a conference call there. One table was abuzz with high school students animatedly discussing their summer projects. The topic? Machine learning algorithms. As I listened, a thought struck me: these young minds are poised to enter an industry in constant flux, with opportunities just waiting for the right skills. This chance encounter led me to explore the best online resources available to help them harness their potential in computer science.
