What is the future prospect of functional websites?

Consider the original goal of the Internet: to help people accomplish certain tasks through convenient means. The emergence of websites later turned these nodes into concrete tools that assist people in completing their work. We call them functional websites, which typically meet user needs based on some tangible function, such as train schedule inquiries. However, new things on the Internet today are increasingly disdainful of being categorized as functional websites, or the scope of new Internet services is becoming increasingly broad. In this situation, good functional websites, especially Internet services created specifically to enhance the experience of a particular function, are becoming fewer and fewer.
