Why learn agents from scratch

AI agents are where software is going. Soon every product you use will have one inside it, and the companies that visit your campus are already building them. In interviews this year they are not asking what an LLM is. They are asking how you would build an agent: the loop, the tools, the memory, and what happens when it fails. They do not want you to start from the basics. They expect you to know these parts already. And once you do, building an agent is easy. Frameworks change every few months; the loop underneath has not changed since 2022.
