The "blurring" framing makes Simon's tension sound intrinsic when it is actually structural. Vibe coding and agentic engineering aren't on a continuum. They're distinguished by the process.

Engineering is always about a defined process. We follow it to produce predictable artifacts that meet the specifications. Even though code is somewhat "squishy" in that it is an art just as much as a science, it still has to meet the spec.

This has always been true, even before agents started writing code for us. We've all dealt with spaghetti code because of undisciplined practices. That's exactly why we came up with the standard SDLC process: plan, design, code, test, deploy. Repeat.

The part people seem to forget about when looking at this is the space between the steps: the gates. We review the artifacts produced at each stage. If the reviewer does not approve, the engineer has to fix it until it passes. True for human coders, doubly true for agentic coders.

Agentic engineering still follows the process. Artifacts are now cheap to produce, which means we have to adjust it so we don't overwhelm the humans in the loop. For me, this means augmenting my review step with agentic reviewers to catch the dumb stuff. It only escalates to me when either a) it passes clean or b) there is something that genuinely needs my experience.

This is agentic engineering, not vibe coding.
