"Ajax ne peut pas tout faire. Les applications web ont encore du chemin à faire."

Simplified Meaning:

Ajax is a technology used to make web applications faster and more interactive. However, it can't solve all the problems that come with building complex websites. For example, think of a smartphone that has amazing features but still sometimes crashes or runs out of battery quickly. Similarly, even with Ajax, web applications might still have issues like being slow or not working well on all devices. In history, every new tool or technology was seen as a miracle fix at first. For example, when cars were first invented, people thought they would solve all transportation problems, but they brought new challenges like traffic and pollution. The same goes for Ajax in web development; it makes things better, but developers still need to keep working on improvements. If you're creating a website, use Ajax to enhance user experience, but also focus on other important aspects like security, compatibility, and ease of use. This balanced approach will help you build a more reliable and efficient application.
