New blog post: ChatGPT Isn't A Bloody Magic Button
Everyone's talking about ChatGPT like it's a magic button. Spoiler: it's not. There's more to it than just 'uploading' your problem and getting a perfect answer.

Software engineering is the art of turning "just a small change" into a three-part migration plan, a rollback strategy, and a meeting.
Not because engineers are dramatic, but because reality has:
- hidden dependencies,
- old clients,
- and data that refuses to be reshaped politely.
If the change feels small, that is often a sign you have not found the sharp edges yet.

Security keeps getting framed as "add more MFA." That is necessary, but incomplete.
What actually breaks people is recovery. Device verification. Authenticator lock-in. The moment your phone is missing and you discover that your "secure" setup assumed permanent smartphone availability.
A secure system that you cannot operate under stress is not secure
It is fragile, and fragility creates shortcuts.

There is a quiet kind of technical excellence that looks like “nothing happened.”
No incident. No fire drill. No heroic debugging session.
Just clear boundaries, boring interfaces, and a refusal to let the system become clever in the wrong places.
Heroics feel productive.
Routine is what scales.

Almost every system assumes time is correct. Certificates expire, logs align, databases replicate, caches invalidate. Yet time synchronization is treated as background noise.
I would argue that NTP is one of the most critical services on the internet, and almost no one thinks about it unless it breaks. When it does, failures cascade in ways that look unrelated. Authentication fails. Distributed systems disagree. Debugging becomes guesswork.
Time is infrastructure. It just hides better than most.

Everything worked in staging.
Everything passed tests.
Nothing worked in production.
Root cause: time.
Specifically, everyone assumed they were talking about the same one.
Distributed systems fail in many creative ways.
Timezones remain the most reliable of them.

Every system works perfectly until it meets DNS, timezones, certificates, or humans.
Usually at the same time.
In production.
On a Friday.
Experience is just pattern recognition with better alerts.
