The Return to Bare Metal: Why We’re Done Pretending

For the better part of two decades, we’ve been sold a story about developer productivity. The pitch went something like this: interpreted languages and high-level frameworks abstract away the complexity of systems programming, letting developers move faster and focus on business logic rather than memory management. Python, JavaScript, and their various runtime environments became the default choice for everything from web services to data pipelines to mobile applications.

It was always a questionable argument. But now? It’s demonstrably false.

The Productivity Myth Is Cracking

The promise was simple: sacrifice some performance for massive gains in developer velocity. Write less code, ship faster, iterate quickly. For a while, we accepted this trade-off without much scrutiny. But something interesting has happened in the last few years—the equation has fundamentally changed.

Modern systems languages like Rust and Go aren’t your grandfather’s C++. They’re not asking you to manually manage memory while avoiding buffer overflows and wrestling with arcane build systems. Rust gives you memory safety without garbage collection. Go gives you simplicity and concurrency primitives that actually make sense. Even C++ itself has evolved dramatically, with header-only libraries providing sophisticated functionality without the dependency hell that plagued earlier generations.

Meanwhile, what’s happened to those “productive” interpreted languages? Try setting up a modern Python environment with the right versions of dependencies across development, staging, and production. Enjoy npm’s nested dependency trees and the regular supply chain attacks. Marvel at the complexity of configuring a React Native or Flutter build system that actually works consistently across platforms.

The supposed productivity advantage has evaporated. In many cases, it’s reversed.

The Security Nightmare We’re Not Talking About Enough

Let’s address the elephant in the room: interpreted languages and hybrid frameworks are security disasters waiting to happen, and in the mobile world, they’re active crime scenes.

Every layer of abstraction is an attack surface. Every runtime is a potential vulnerability. Every dependency is a liability. When you build on Node.js, you’re trusting thousands of packages written by strangers, many of which haven’t been maintained in years. The JavaScript ecosystem has normalized supply chain attacks to the point where they barely make headlines anymore.

Mobile frameworks like React Native and Flutter are particularly problematic. You’re essentially running a JavaScript engine or a Dart VM inside a mobile application, adding massive complexity to your security model. Every bridge between the runtime and native code is a potential exploit vector. Every third-party plugin is a black box that could be doing anything.

Native code—code that compiles directly to assembly—has a much smaller attack surface. Yes, you can still write insecure native code. But you’re starting from a fundamentally more defensible position when your entire application isn’t dependent on a runtime environment with its own vulnerabilities and an ecosystem of questionable dependencies.

The Performance Trap

Here’s the ultimate irony: even teams that choose interpreted languages for their supposed productivity eventually hit performance walls that force them to write native extensions anyway.

Your Python data pipeline is too slow? Time to write C extensions. Your Node.js service can’t handle the load? Better reach for native modules. Your React Native app feels sluggish? Guess you’ll be writing native modules for the performance-critical paths.

So you end up doing the very thing you claimed to avoid—writing native code—but now you’re doing it in the worst possible way. You’re maintaining a hybrid codebase with all the complexity of interfacing between different languages, managing the build systems for both environments, and debugging across the boundary between interpreted and native code.

If you’re going to write native code anyway, why not just start there?

We’re at an Inflection Point

The combination of mature systems languages, deteriorating security postures in interpreted ecosystems, and the collapse of the productivity argument means we’re at a genuine inflection point.

The right question isn’t “Can we afford to use Rust or Go?” It’s “Can we afford not to?”

When you choose your technology stack, you’re making a bet about the future of your project. You’re deciding what kinds of problems you’re willing to deal with three years from now. Are you betting on dependency hell, security vulnerabilities, and performance bottlenecks? Or are you betting on a compiled binary that does exactly what it’s supposed to do, nothing more, nothing less?

Time for Hard Questions

It’s time to re-examine the assumptions that have driven platform and development decisions for the past decade:

Is this stack actually more productive? Not in theory, not based on a blog post from 2015, but in reality, on your team, with your problems. Are your developers spending more time wrestling with the framework than solving problems?

What is the true security posture? Not just “we run security scanners,” but what is your actual attack surface? How many dependencies are you trusting? How many have known vulnerabilities right now that you haven’t patched?

Are you being honest about native code requirements? If you’re already writing native extensions for performance, why are you maintaining the fiction that you’re avoiding native development?

What is your five-year maintenance story? Will this framework still be maintained? Will you be able to find developers who know it? Or are you building on shifting sand?

The Path Forward

This isn’t about religious devotion to compiled languages or rejecting all abstraction. It’s about making clear-eyed technical decisions based on current reality rather than outdated assumptions.

Rust and Go have proven that systems programming can be accessible. Header-only C++ libraries have shown that native development doesn’t require nightmarish dependency management. The tooling has matured. The communities have grown. The libraries exist.

The case for choosing interpreted languages by default has collapsed under the weight of its own contradictions. We pretended they were simpler—they’re not. We pretended they were more secure—they’re less. We pretended they let us avoid native code—they don’t.

It’s time to stop pretending and start building on solid foundations again. The bare metal is calling, and it’s never been more inviting.
