We’re living in a world where software is the invisible infrastructure for daily life. There doesn’t appear to be any quantitative measure of what proportion of everything we use actually contains software, but it’s not outrageous to assert that almost everything we use depends on it. Whatever the real proportion is, with the advent of AI and the Internet of Things (IoT) it’s only climbing. Software has blossomed from primitive beginnings to become crucial in every facet of life in less than 75 years. In the 1950s software wasn’t a ‘product’ but something bundled with hardware used primarily for scientific calculations, military simulations, and data processing. Most of it was written in machine code or early assembly languages tailored to specific hardware, and it was written by the same engineers who built the hardware. A large program was a few thousand lines of code loaded manually via cards or magnetic tape. FORTRAN only emerged in 1956 and the term ‘software engineering’ was only coined in the late 1960s/early 1970s.
How things have changed. Today’s internet, search tools, social media, cars, medical devices, satellites, aircraft, trains, weapons, smartphones and so on depend on many, many millions of lines of code, see here and here for example. Modern health, financial, energy, government, intelligence, and defence capabilities all rely on huge amounts of software. Indeed, any item in our homes that can sync with a smartphone app contains software. In less than 75 years software has changed life, taken over the world, and become professionalised in the way it’s produced. Writing machine code for specific hardware in a way that ‘every byte counts’ has evolved into the professional, ever changing and improving, discipline of software engineering which incorporates design and development processes, methods, standards, tools and techniques that ensure that production software meets requirements, is scalable, tested, robust, maintainable, secure, and performant. Software engineering, of which coding is today just a subset, continues to evolve with, for example, the likes of Microsoft and Google anticipating that AI will render hand crafting of code redundant by the end of this decade.
The software woven into our lives in recent decades has brought immense convenience and transformed communication, public services, business, and conflict, as world events illustrate. Today it’s undeniably critical infrastructure, but software, unlike most infrastructure, isn’t something you can tangibly touch! Compared to what existed 75 years ago, the software in use today is a vulnerable sprawling metropolis with vulnerabilities that bad actors can use to cause disruption. Are we safer today than in the 1950s now that everything depends on software? Hmm, that’s debateable, but what the Badger senses is that even with the advent of AI, software engineering as a discipline and the career prospects for software engineers focused on solutions, security, quality, robustness, and testing rather than coding, are good for many, many years yet…
