In this video, I discussed the balance between rewriting code from scratch and reusing existing solutions. While engineers often prefer to build from the ground up, it's not always the best approach. I highlighted three common reasons for rewriting—outdated solutions, difficult setups, and complex codebases. However, I emphasized that existing tools, with strong community support, usually offer long-term advantages. Rewriting is justified when the current code is outdated or a critical bottleneck, but the benefits must outweigh the investment.
