But while we are busy chasing the shiny new tools, we often neglect the bedrock of our profession: Computer Science Fundamentals. The reality is that frameworks are ephemeral, but fundamentals are eternal. Let's dive into why betting on the core concepts is the best investment you can make for your engineering career.
