AI Agents have brought the execution cost of software engineering down to almost zero. Now, all you need to do is tell the Agent, 'Handle JIRA-1234,' and it will automatically fetch the task, create a plan, complete the commit, and even have another AI session handle the review process and point out issues. This closed-loop workflow has compressed development cycles that used to take hours into just minutes. The next variable is: when the barrier to code generation disappears, will your ability to master complex system architecture become the only moat?
