> must thin[k] agentic loops don't exist, kind of a weird take for the people that have been using them for the last year or two

How was their take weird?

LLMs take input and generate output. Agentic loops tells you what it is doing right there in the name. The agent (software, think complex scripts and control flow functions) `loops` the llm output back into llm input until it gets output that it is processable (activates a tool call control flow element). That ruminated (as in cud chewing, not human deep thinking) processable llm output data is moved along as input for tools (more software but ones that actually do the things) that are part of a larger infrastructure of software and may or may not `loop` back over the process some more. The llm is simply a human text generator tool providing randomized data to feed into these tools that were also built for humans and thus take text input.

The initial llm data seed does not spontaneously appear, nor does the software infrastructure that makes it all happen. We have simply automated the human text input part of tool use by building a text generator tool that breaks down all the individual tool calls we would have had to do ourself and gave it a loop.

The greater focus needs to be on better engineering of the surrounding software infrastructure (including network and loops) because without those sticks and stones a bunch of generated words isn't going to be hacking anything, except maybe feelings and the minds of those prone to fantastical flights of fancy.
