> "knowing how to search" used to be a skill

I would argue this was always a bit silly, and mostly due to UI shortcomings of search platforms. The fact you needed to add "magic" params to shape the results speaks volumes. Any UI that fundamentally tries to reshape how you are expect to interact, or impose certain "behavior" is wrong. This is also why we are using touch instead of a stylus.

AI won because they took the paradigm of presenting a new way of doing something in a familiar way. An LLM works very similarly how you would ask a knowledgeable friend, and google worked similarly how an engineer would query a database.
