Ask a group of developers why they chose a particular tech stack, and you’ll hear answers like:
- “It scales better.”
- “It’s faster.”
- “It’s more modern.”
- “It’s industry standard.”
But here’s the uncomfortable truth most people won’t say out loud:
Most tech stacks are not chosen because they’re technically superior.
They’re chosen because of people.
And once you see this, you can’t unsee it.
The Myth of the “Best Stack”
We like to believe software decisions are rational.
That if you compare performance benchmarks, ecosystem maturity, and scalability charts, one stack will clearly emerge as the best choice.
In reality, most modern stacks are good enough.
React, Vue, Angular.
Spring, Node, Django.
Postgres, MySQL, MongoDB.
At a certain point, the differences stop being decisive.
So why do teams still argue so passionately about stacks?
Because the decision isn’t really about code.
It’s about people, trust, incentives, and fear.
Stack Choices Are About Who You Can Hire
One of the most influential — and least discussed — reasons stacks are chosen:
“Can we hire for this?”
Not:
- “Is this the most elegant solution?”
- “Is this the cleanest architecture?”
But:
- Are there developers available?
- Can new hires onboard quickly?
- Will this scare candidates away?
A technically “better” stack that no one knows is often a business liability, not an advantage.
Teams don’t choose stacks that are optimal.
They choose stacks that are survivable.
Familiarity Beats Excellence Every Time
Here’s a hard truth:
Teams prefer stacks they understand over stacks that are better.
Why?
Because familiarity reduces:
- Risk
- Fear
- Decision fatigue
- Accountability
If something goes wrong with a familiar stack, everyone knows how to debug it.
If something goes wrong with a “clever” stack, someone gets blamed.
So people default to what they’ve used before — not because it’s best, but because it’s defensible.
Tech Stack Decisions Are Political (Yes, Political)
In many companies, stack choices are shaped by:
- The loudest voice in the room
- The most senior engineer
- The architect’s past experience
- A previous company’s success story Sometimes the stack is chosen simply because:
“This is what we used at my last job, and it worked.”
That’s not technical reasoning.
That’s social proof.
And it’s incredibly powerful.
“Modern” Often Means “Socially Accepted”
Notice how stacks suddenly become “modern” when:
- Big companies adopt them
- They're always mentioned by influencers
- Job postings mention them
Modern doesn’t mean better.
It often means safe to choose without explanation.
Choosing a popular stack protects decision-makers.
If it fails, they weren’t reckless — they followed the trend.
The Hidden Question Behind Every Stack Choice
What folks really want to know is this:
Not:
- “Is this the fastest?”
- “Is this the cleanest?”
But:
- Might someone point the finger at me?
- Could this slow down recruitment?
- Could this make starting take longer?
- Could this complicate things for the team when upkeep rolls around? These are human concerns, not technical ones.
This Is Why Stack Debates Never End
Ever noticed that stack debates rarely reach agreement?
That’s because you’re not debating code.
You’re debating:
- Identity
- Experience
- Ego
- Risk tolerance
Two developers can look at the same problem and choose different stacks — both for valid social reasons.
And neither is “wrong”.
Why This Matters (Especially for Developers)
Understanding this changes the way you think about:
- Career growth
- Learning priorities
- Project decisions
It explains why:
- “Worse” stacks survive
- “Better” stacks die
- Legacy systems persist
- Simple tools dominate
It also explains why learning only the “best” technology isn’t enough.
What matters is:
- Can teams work with it?
- Can people maintain it?
- Can the organization support it?
The Real Skill Isn’t Choosing the Stack
The real skill is knowing when stack choice matters — and when it doesn’t.
Great engineers don’t obsess over tools.
They think about:
- Teams
- Communication
- Longevity
- Change
They understand that software lives longer than trends — and people live longer than code.
Final Thought
If you’re early in your career, this is freeing.
It means you don’t have to chase every “hot” technology.
You don’t need the perfect stack.
You need to understand trade-offs, people, and context.
Because in the real world:
The best stack isn’t the one with the best benchmarks.
It’s the one the team can actually build, maintain, and evolve together.
I’m curious — and this is where the best discussions start :)
Have you ever seen a “technically better” stack lose to a more familiar one?
Why do you think that happened?

Yeah… this is painfully accurate, and once you see it, you really can’t unsee it.
I’ve been on both sides of this. Early on, I genuinely believed stack choice was about “doing it right” — better abstractions, cleaner architecture, nicer performance curves. Over time, what actually kept surfacing wasn’t benchmarks… it was people. Who understands this? Who can maintain it when I’m gone? Who’s going to get blamed if this explodes in prod?
The hiring angle is huge and rarely said out loud. A stack can be technically elegant and still be a liability if onboarding takes months or candidates flinch when they see it. Teams don’t optimize for theoretical excellence, they optimize for survival. And honestly, that’s rational.
The political part is real too. I’ve watched stacks win simply because one senior person had prior success with it. Not because it was perfect — but because it was defensible. If it breaks, it’s “industry standard.” If a clever choice breaks, it’s “why did you over-engineer this?”
What clicked for me over time is that “modern” mostly means “safe to explain in a meeting.” Social acceptance beats novelty almost every time. Trends become shields.
This perspective also changed how I think about learning. Chasing the “best” tech in isolation misses the point. What actually compounds is understanding trade-offs, context, and how systems age inside organizations full of humans with incentives, fears, and deadlines.
So yeah, I’ve absolutely seen technically better stacks lose — not because they were bad, but because they demanded more trust than the environment could give. And that doesn’t make the decision stupid. It makes it human.
Good post. This is the kind of framing that saves people years of confusion.

You I'd prefer organic content... At least it feels like human...
