Standing on the narrowest wooden platform, twelve feet above the floor of the nave, I could feel the low C pipe begin to rattle against its housing before I could actually hear it. It was a vibration that started in my teeth and worked its way down to my shins.

I reached out a hand, calloused from 28 years of adjusting tin and lead, and pressed my thumb against the vibrating seam. The rattling stopped, replaced by a pure, terrifyingly deep tone that felt like the earth itself was clearing its throat.

If you miss the frequency by even 8 hertz, the whole chord collapses into a muddy, discordant mess. Every adjustment matters because the room is a living participant in the sound.

The Frankenstein’s Monster of Expectations

This morning, I counted exactly 48 steps from my front door to the mailbox. It was a cold morning, the kind that makes the metal of the mailbox bite into your palm. Inside, among the bills and the flyers for lawn care, was a letter from a former apprentice who had left the world of acoustics for the world of software.

He was writing to me about his frustration with a job posting he had seen. He described it as a “Frankenstein’s monster” of expectations. It asked for someone who understood the manual testing rigors of 2008, the Selenium-heavy automation of 2018, and the agentic, AI-driven infrastructure that is projected for 2028.

He didn’t know which version of himself to present. He didn’t know which path would lead to a career and which would lead to a dead end. I told him what I tell every young tuner: the instrument is changing, and if you don’t decide which part of the sound you want to own, the room will eventually swallow you whole.

The QA profession is currently undergoing a quiet, violent bifurcation. We are witnessing the birth of two entirely different species of engineers who happen to share the same job title.

On one side, you have the practitioners who treat AI agents, agentic execution, and compliance evidence as their primary craft. On the other side, you have those who are still faithfully maintaining Selenium suites and manual CSV exports. Within the next 18 months, these two groups will no longer be doing the same job, and they will certainly not be commanding the same 158-thousand-dollar salaries.

The Tale of Two Engineers

The split starts with a single quarter of choices. Think of two engineers, hired in the same month at the same mid-sized firm. Let’s call them Sam and Alex.

By the end of that year, Sam has maintained the status quo. He is still useful, the way a man who can fix a 1968 boiler is useful. But Alex is leading the platform. He has reduced the testing cycle from 48 hours to 8 minutes.

Crossing the Digital Chasm

I remember when digital organs first started showing up in the smaller chapels. Some tuners refused to touch them, claiming they weren’t “real” instruments. They stayed with the pipes. But the pipes are rare, and the digital systems are everywhere.

The tuners who learned how to program the digital interfaces, how to balance the electronic output with the room’s natural acoustics, are the ones who are still working 48 weeks a year. The others are waiting for a phone call that comes less and less often.

This shift is why we’re seeing such a weird overlap in job postings. Companies are terrified. They have 108 million lines of legacy code and they know they need to move to an AI-native workflow, but they don’t know how to bridge the gap.

The Human Machine Irony

I often think about the 48 steps to my mailbox. Each step is a repetition. Most of QA has been a series of repetitions-manual regression, clicking through the same 8 screens, verifying the same 18 fields.

We have spent the last decade trying to turn humans into machines. Now, we are finally building machines that can act with a semblance of human agency. The irony is that this requires the humans to become more human, more strategic, and more focused on the high-level architecture of quality.

I’ve made my share of mistakes. I once spent 8 days trying to tune a pipe that was actually just blocked by a dead starling. I was so focused on the frequency that I forgot to look at the physical reality of the object.

“QA engineers make this mistake every day. They focus on the ‘test pass rate’ and ignore the fact that the entire testing strategy is blocked by a dead methodology.”

They are polishing the scripts of a dying world. The bifurcation is already here. You can see it in the way people talk at conferences. One group is talking about “flaky selectors” and “browser versions.” The other group is talking about “context windows,” “inference costs,” and “agentic drift.”

Resonating in Tune

I’m an old man now, and my knees ache after 48 minutes on a ladder. But I still know when a room is in tune. I know when the vibrations are right. The software world is currently out of tune. It’s vibrating with the tension of a massive shift. You can feel it in your teeth.

When I finished tuning that low C this morning, I sat on the platform for a long time, just listening to the silence. A well-tuned organ makes the silence feel heavy, like it’s full of potential energy. That’s what a good QA system should feel like. It shouldn’t be a source of noise or constant “flaky” alerts.

It should be a quiet, powerful foundation that allows the rest of the application to sing.

If you find yourself in 2028 still fighting with CSS selectors, remember the pipe organ tuner. Remember that the world didn’t stop needing music; it just started making it in a different way. You have to decide if you want to be the one who polishes the pipes or the one who knows how to make the whole building vibrate with the perfect chord.

One of those jobs is a hobby for the nostalgic. The other is the future. I know which one I would choose if I were starting my 48 steps all over again.
