LLMs allow humans and computers to talk naturally and understand each other.

This is new!

For a long time, humans had to learn a very challenging and unforgiving foreign language to talk to a computer, and it never felt completely natural.

The same was true for computers to talk to humans.

LLMs allow users to express their situated needs and goals at way less cost and challenge than before, in a way the computer can natively understand.

This allows the human to give a high level sketch of what they want and have the system choose reasonable details, automatically.
