Very powerful
So basically llm cannot replace code
Code / program is still the foundation
The building blocks
They extend language
The power of agents is that it can translate natural language to tool calls and so text processing
So non programmers can do things with natural language
And could do complicated things with easy ask
Llm provided generic interface
But underlying implementation requires curated knowledge
Which is sample codes, instructions, references, prompts
