The Dark Ages: Programming Before Modern Tools

To understand how revolutionary today's AI-powered development is, you need to see where we started.

In the 1940s and 1950s, programming meant:

Physical punch cards for every line of code
No screens, no keyboards, no immediate feedback
Mistakes meant starting over completely
Programs took days or weeks to test once

A single typo could waste weeks of work.

The Foundation Years (1940s-1960s): Where Software Development Began

Software development didn't start with a grand vision. It started with mathematicians trying to solve specific problems faster.

The Birth of Programming

1940s: The First Programs

ENIAC (1946): Required physical rewiring to change programs
Stored Program Concept: Programs could be stored in memory like data
Machine Language: Direct communication with hardware using binary

The problem: Programming was incredibly tedious and error-prone. Making changes required understanding hardware at the deepest level.

Assembly Language: The First Abstraction

Late 1940s: Making Code Human-Readable

Instead of writing:

10110000 01100001

Programmers could write:

MOV AL, 97

Why this mattered: Suddenly, humans could read and understand code. This was the first step toward making programming accessible.

The Compiler Revolution

1950s: High-Level Languages Emerge

FORTRAN (1957): The first commercially successful high-level language
