Week1 - LLM as Fresh college graduate

In Week 1’s video, Andrew used the fresh college graduate analogy to help understand what LLM can/cannot do. But I’m confused about the first assumption of no access to the internet or other resources. LLM doesn’t have company specific data/info but it does have internet info as that is where it is trained from. Not sure why we think of LLM as fresh college graduate without access to internet.

Assume that the LLM has already been trained, and does not need live internet access to answer queries.
