Liquid modernity did not begin with the internet, but the post-LLM web is turning social fluidity into computational infrastructure. This essay argues that the fragmentation of identity, work, relationships and institutions is no longer simply a social phenomenon. Through the Asymmetric Integration Model (AIM), it proposes that these forms of human fluidity are increasingly being instrumented, optimised and integrated into computational systems, signalling the emergence of a new phase in the evolution of the web and its relationship with society.
