Stack Overflow: The invisible platform engineer: why developers still need human interaction

Reality bites

But the reality is that autonomy doesn’t eliminate complexity; it simply shifts it. 

Behind every polished self-service interface lies a web of orchestration, governance and integration that someone must design, maintain and evolve. That “someone” is the platform engineering team, the often-invisible layer of expertise that makes autonomy possible.

Human factors in self-service 

The hype around automation and AI-driven workflows can obscure a fundamental truth: developers still need human interaction. According to the 2025 Stack Overflow Developer Survey, 75% of developers say they prefer to consult another person when they don’t trust AI-generated answers, even though 84% use AI tools in their workflows. 

Why? Because trust, context and collaboration remain irreplaceable.

This preference isn’t just about debugging code. It reflects a deeper need for shared understanding – something no portal or chatbot can fully replicate. Developers want to know why a solution works, not just that it does. They value mentorship, peer review and the reassurance that comes from human judgment. In fact, 62% cite ethical or security concerns as reasons for seeking human input and 61% say they want to fully understand their code before shipping it.

Platform teams: the multiplier effect

Self-service doesn’t mean self-sufficiency. IDPs are not “set it and forget it” solutions; they require continuous iteration to stay relevant. 

Successful platform engineering teams treat their platforms like products, complete with roadmaps, user research and feedback loops. They embed themselves in development teams, observe pain points firsthand and “design golden” paths that balance autonomy with guardrails. When done well, these teams act as multipliers for the entire engineering organisation – their work compounds across every team they serve.

This work is invisible by design. When an IDP functions well, developers barely notice the orchestration behind the scenes. But the effort involved is substantial: integrating CI/CD pipelines, enforcing security policies, managing secrets and ensuring compliance – all while abstracting complexity away from the end user.

Without this connective tissue, self-service quickly devolves into chaos: inconsistent environments, duplicated tooling and mounting technical debt.

Tools alone aren’t enough

The temptation to view platform engineering as a tooling problem is strong. Drop in a portal like Backstage, add a catalogue of services and declare victory. However, adoption is rarely that straightforward. Developers usually stick with what they’re comfortable with. Changing habits requires more than shiny interfaces – it requires building tools developers want to use, not tools they have to use. The goal is to create gravitational pull towards your solutions rather than forcing compliance.

Organisations that succeed with self-service treat developers as customers. They invest in onboarding, documentation and support. They build standardised abstractions that let developers learn once and apply everywhere. 

They measure adoption, retire unused features and iterate based on real-world feedback, not assumptions. In short, they recognise that platform engineering is as much about people as it is about pipelines.

Data-driven reality check

The 2025 Developer Survey demonstrates that while automation dominates news headlines, human-centric practices remain critical. Developers are actively upskilling, with 69% of users spending time learning new languages or techniques last year and community platforms such as Stack Overflow remain thriving ecosystems of learning and collaboration, with 84% of respondents using it for peer-reviewed answers.

Notably, 35% turn to Stack Overflow after encountering issues with AI-generated responses, reinforcing the enduring value of human expertise.

This isn’t nostalgia; it’s pragmatism. AI tools can accelerate workflows, but they also introduce new risks: hallucinated outputs, opaque reasoning and ethical blind spots. Developers know this and they compensate by leaning on trusted human networks.

Platform engineers play a similar role internally – they unstick organisations, provide the guardrails that keep autonomy safe and create the foundation for engineering teams to move faster.

The future: human-centric automation

So where do we go from here? The answer isn’t to roll back self-service or dismiss automation, but to find a path forward that includes designing systems that amplify human strengths rather than replacing them. 

This approach entails:

• Embedding platform engineers in product teams to surface real pain points and co-create solutions.
  
• Treating IDPs as living products, with continuous feedback loops and clear ownership.
  
• Balancing autonomy with governance, using guardrails that enable experimentation without sacrificing security or compliance.
  
• Investing in developer experience (DX) as a first-order priority, recognising that cognitive load is as real a constraint as compute cycles.

Self-service is powerful, but it’s not a panacea. 

Behind every frictionless workflow is a team of humans making hard decisions about architecture, security and usability. Great platforms build great cultures – and great cultures are built by people, not portals. They may be invisible, but they are indispensable.
