We're about to learn a painful lesson about delayed gratification in software engineering.

New data from China, 26,811 students tracked January 2023 through June 2025. Students using AI for homework saw their scores jump 20 percent. Completion time dropped nearly half. They aced the assignments.

Then exam season came. Those same students scored 20 to 40 percent worse when they couldn't use the tool.

The homework phase is over. The exam phase is coming.

We're doing this in software right now. Vibe coding feels incredible. Features ship fast. Nobody's asking what happens in Month 18 when the original dev has left and nobody understands the codebase.

Commercial pilots fly with autopilot for most of every flight. They're required to maintain manual flying proficiency regardless. If the system fails mid-air and the pilot can't take over, people die.

Most teams using AI right now have forgotten how to fly manually. They've become passengers in their own systems. The autopilot flies, nobody checks instruments, and the first sign of trouble will be a breach notice or outage.

Three rules:

  1. Command the mission. Define architecture before prompting. Ambiguity kills in code and in flight. Delegate selectively. Offload mechanical work. Keep design and security reviews human. Verify everything. Audit before production.
  1. Never trust the automation without checking instruments.
  1. Quick wins feel good. Sustainable engineering feels boring. Boring keeps systems standing.

Organisations surviving the next two years won't ship the fastest. They'll be the ones who remember how to fly without the aids.


people insisting that you actually be skilled, independently of your tools, doesn't make them Luddites. Rather, being unable to do so makes you a phony.

I try vibe coding from time to time and it’s a mixed bag. When it works it works but then there’s suddenly just code there. It’s like when a colleague implements a feature in a project with multiple devs but since it’s just your personal project you suddenly got put in the code reviewer chair.

When I write code I reason about all the small decisions but when the agent takes over I have to figure out step by step why decisions were made.

I’m still not sold on coding agents and vibecoding but it’s getting better and more usable. The only downside is that a agent doing its thing is now seen as downtime where you could just prompt another agent and work on several projects simultaneously. If anyone ever tells you vibecoding is good because you can work in parallel RUN
