Why is the "Bay-like" structure of Dubai Islands a technical improvement over the original Palm?

The full explanation

Dubai Islands is not just a replica; it is an evolution that fixes the technical flaws of previous offshore projects. The islands use a "bay-like" structure that facilitates better water circulation, which effectively weeds out the problem of stagnant water. This ensures that residents have cleaner beaches and a healthier aquatic environment. Furthermore, whereas the original Palm represents a "choke point" with a single entry and exit, Dubai Islands features three entries to facilitate a smooth flow of traffic. This technical foresight elevates the quality of life and makes the development more sustainable for the 7.8 million residents Dubai expects to house by 2040. As a surgical consultant, I view these infrastructure improvements as the "DNA of longevity" for the asset.
