You’ve probably seen the coding ads. “Get your kid into Python!” they scream, promising future-proof careers and Silicon Valley salaries. So you sign them up. They learn to print “Hello World,” drag some blocks, maybe build a basic web scraper. They are learning syntax. But they have absolutely no idea how a computer actually works.
We are teaching kids to assemble IKEA furniture when we should be teaching them how trees become wood.
If you really want to teach a child computation, you need to throw out the modern playbook entirely. You need to teach them a language that is entirely irrelevant to the modern job market. You need to teach them Forth.
Created in the 1970s, Forth is a stack-based language. It has almost no syntax. You don’t write complex nested parentheses or memorize object-oriented rules. You just push data onto a stack, and pop it off. It is brutally simple and maddeningly difficult.
It is also the closest thing to learning Latin for the digital age.
When you learn Python, you are learning a highly abstracted tool. When you learn Forth, you are learning the structural mechanics of computation itself. The very constraints that make it a nightmare for modern enterprise development—manual stack management, zero hand-holding, extreme minimalism—force the learner to internalize exactly how a CPU processes information.
Syntax is just a dialect. The stack is the soul of the machine.
Even the die-hard fans know this is a crazy idea. In a recent discussion on teaching Forth, one programmer admitted, “I really love Forth and spend almost all my free programming time playing with it and I’d never teach it to a class of kids.” It’s practically career suicide. Why teach a language that no modern company uses?
Because the goal of childhood education isn’t to produce junior React developers. It’s to build cognitive flexibility.
Consider the story of another programmer who reflected on their teenage years programming in RPL, a stack-based language used in old HP calculators. They noted that while it might not be a “useful language” in today’s industry, it fundamentally rewired their brain. It introduced them to the stack, but also to the concept that “everything is an object.” It wasn’t about the syntax; it was about the paradigm shift.
A language that can’t get you a job might be the only one that teaches you how to think.
Mainstream programming education is obsessed with immediate, marketable utility. We want kids to build apps by week three. But this rush to produce functional code skips the foundational understanding of what code actually is. We are creating syntax-monkeys who can Google their way through a Stack Overflow error, but who freeze when confronted with a problem that requires deep algorithmic thinking.
Teaching Forth is an act of rebellion against this fast-food approach to tech education. It says: let’s slow down. Let’s do things the hard way. Let’s strip away the abstractions and stare directly into the mathematical heart of the computer.
Your kid probably won’t write a SaaS app in Forth. But when they eventually pick up Python, Rust, or C++, they won’t just be reciting incantations. They will understand the machine beneath the magic.
FAQ
Q: Isn't teaching a dead language a waste of a kid's time?
A: No, because the goal isn't workforce training; it's cognitive development. You don't teach kids Latin so they can order coffee in Rome. You teach it to rewire their understanding of grammar and structure. Forth does the exact same thing for computation.
Q: How does learning Forth practically help a child later on?
A: It strips away the magic of modern abstraction. When a kid manually manages a stack, they internalize memory allocation and execution flow. When they eventually use Python or JavaScript, they understand what the interpreter is actually doing under the hood, making them vastly better debuggers and architects.
Q: Are you saying Python and modern languages are bad for kids?
A: They are great for building things quickly, but terrible for teaching foundational mechanics. Relying solely on high-level languages creates a generation of programmers who can assemble blocks but panic when the abstraction leaks. Forth forces you to face the bare metal.
