We’ve all heard it: “Knowing COBOL or VB6 doesn’t count anymore.”

Funny thing is, people who say that usually forget that half the world still runs on those technologies — banks, governments, insurance systems, healthcare, all of it.
And behind that code are devs who’ve been solving real-world problems for decades, keeping critical systems alive while the rest of us argue about which JavaScript framework is slightly less awful this year.

They’re not outdated. They’re battle-tested.

The Bootcamp Paradox

Nothing against bootcamps — they open doors for a lot of people.
The issue is how the industry glorifies “modern stacks” while ignoring experience that actually matters.

A junior who knows React and a bit of Node.js might get more interviews than a dev who spent 20 years optimizing financial systems in COBOL.
That’s not logic — that’s marketing.

And here’s the twist: the learning curve for an old-school dev picking up modern tech is usually shorter.
They already understand logic, databases, concurrency, and performance.
They’ve debugged disasters at 3 AM with no Stack Overflow link to save them.
Learning a new syntax? That’s the easy part.

Reinventing the Wheel (Because You Had To)

What most people don’t realize is that legacy devs had to reinvent everything.
In environments like COBOL or Progress 4GL, there were no libraries, no frameworks, no “npm install something-that-solves-it-for-me”.

If you needed to parse a JSON file, you couldn’t just do import json.
You had to build the damn parser yourself.

That teaches a different mindset — you start thinking like an engineer, not just a code implementer.
You learn to build tools, not just use them.

So when those same devs jump into Node.js, Go, or Python, they adapt fast — because they already understand how things work under the hood.

The Bottom Line

Software changes every year, but fundamentals don’t.
A dev who’s survived multiple tech eras and still stays curious is worth a lot — not for nostalgia, but for what it represents:
technical resilience and adaptability.

Those are things no bootcamp can teach in three months.
