The way I see dependency in office ("knowledge") work:

- pre-(computing) history. We are at the office, we work

- dawn of the pc: my computer is down, work halts

- dawn of the lan: the network is down, work halts

- dawn of the Internet: the Internet connection is down, work halts (<- we are basically all here)

- dawn of the LLM: ChatGPT is down, work halts (<- for many, we are here already)
