In the 1970s, when Microsoft and Apple were founded, programming was an art only a limited group of dedicated enthusiasts actually knew how to perform properly. CPUs were rather slow, personal computers had a very limited amount of memory, and monitors were lo-res. To create something decent, a programmer had to fight against actual hardware limitations.
In order to win in this war, programmers had to be both trained and talented in computer science, a science that was at that time mostly about algorithms and data structures. The first three volumes of the famous book The Art of Computer Programming by Donald Knuth, a Stanford University professor and a Turing Award winner, were published in 1968-1973. This programming bible earned a famous comment from Bill Gates: "It took incredible discipline, and several months, for me to read it."
This comment demonstrates the reality that creating a simple piece of software was a complex engineering task, even though software engineering only "emerged as a discipline in its own right" later on in the 1980s, as Ian Sommerville said in his 1982 book Software Engineering.
Most programmers were calling themselves "hackers," even though in the early 1980s this word, according to Steven Levy's book Hackers: Heroes of the Computer Revolution, "had acquired a specific and negative connotation." Since the 1990s, this label has become "a shibboleth that identifies one as a member of the tribe," as linguist Geoff Nunberg pointed out.
Being able to hack both the software and the hardware was a virtue for a long time. However, the world of computer programming has changed dramatically in the last decade.
First of all, the cost of computing power gets cheaper every year. For example, one gigabyte of computer memory cost about $1,000 in 2000. In 2018, it costs less than $5. That is 200 times cheaper in the span of only 18 years. The same is true for hard drives, monitors, CPUs, and all other hardware resources. As James Somers noticed in his analysis of industry problems in The Coming Software Apocalypse: "Computers [have] doubled in power every 18 months for the
last 40 years."
Second, the growth of open source is massive. The majority of software is available for free now along with its source code, including operating systems, graphic processors, compilers, editors, frameworks, cryptography tools, and whatever else we can imagine. Programmers do not need to write much code anymore; all they need to do in most cases is wire together already available components.
Third, despite an increasing population of programmers in the world, the field is still in a deficit. In some European countries, the demand for highly-skilled IT personnel is twice as high as their market supply of talent. According to Iamexpat.nl, in the Netherlands "a whopping 76% of HR employees reported having difficulty finding enough candidates with this qualification."
Fourth, programmers now work remotely instead of in offices or cubicles. Thanks to the growth of high-speed Internet, conferencing software like Zoom and Skype, messaging tools like Slack and Telegram, and distributed repository managers like GitHub and Bitbucket, along with many other innovations, remote work has become more comfortable than the alternative of working in the traditional office setting.
Finally, programmer salaries have skyrocketed in the last few decades. In 2000, when one gigabyte of memory still cost $1,000, the average senior programmer earned around $80,000 in Silicon Valley. In 2018, they are currently making three times more, while RAM is 200 times cheaper.
Taking these five variables into account, it would appear that the skills required of professional and successful programmers are drastically different from the ones needed back in the 1990s. The profession now requires less mathematics and algorithms and instead emphasizes more skills under the umbrella term "sociotech." Susan Long illustrates in her book Socioanalytic Methods: Discovering the Hidden in Organizations and Social Systems that the term "sociotechnical systems" was coined by Eric Trist et al. in the World War II era based on their work with English coal miners at the Tavistock Institute in London. The term now seems more suitable to the new skills and techniques modern programmers need.
They need to know how to communicate with the open source community to find the needed components, to request features, and to learn bug fixes from their developers. Moreover, they have to be ready to contribute to open source software by submitting pull requests or even creating their own programs. Those who used to work only with commercial and private software will soon be far behind other programmers.
They have to know how to get help outside of an office or even a project team when working remotely and alone. Aside from Stack Overflow, which dominates the Q&A platform for programming market, there are documentation and code repositories that a professional programmer must know how to navigate. Those who previously only relied on colleagues and friends will now lose to those who know how to learn from the entire Internet.
Programmers have to know how to write maintainable code that other programmers will be able to easily understand. Since hiring personnel grows more expensive every year, businesses emphasize the maintainability of their code bases over developing exceptionally complex code. It is easier for them to buy a larger server if the algorithm is not fast enough, rather than lose what previous programmers created when a new team or a replacement shows up and fails to understand how to modify the project. Because the cost of computers continues to grow cheaper and the cost for employing programmers continues to increase, maintainability continues to dominate the programming landscape as the primary virtue of almost any software. The end result is that these "Hackers" who spend their days writing complex, cryptic code will soon find themselves out of the market.
Edsger W. Dijkstra's words—"Simplicity is a great virtue"—which he uttered in 1984, grow increasingly more valuable every year.
It seems that the future of programming rests less in math and more in sociotech relationships between people.
