The rapid evolution of technology and its integration into various sectors continues to drive the expansion and diversification of computer science (CS) fields. As we stand on the cusp of a new era of digital innovation, it’s crucial to forecast which specializations within CS will dominate the limelight in the forthcoming years. Especially since the craze for IT specialists has died down a bit due to the significant influx of new workers in the field. That’s why the question posted on Reddit regarding the fields in CS that are set to experience significant growth, makes perfect sense.

Key Takeaways

  • While there’s a general emphasis on sticking to the fundamentals of computer science, specific fields like security, distributed systems, AI, and ML are projected to see significant growth in the near future.
  • The global technology market is expected to reach USD 3168.13 million by 2027, driven by advancements in big data analytics, cloud computing, and IoT, indicating robust growth in computer science-related occupations.
  • Despite current market saturation concerns, the overarching sentiment remains positive, with computer science continuing to influence various sectors and present numerous opportunities for both current and aspiring professionals.

We see a lot of stories about how the field of computer science has now oversaturated with new specialists. This raises a natural question:

The OP, trying to figure which path to choose with their studies, turned to Reddit and the platform users weren’t hesitant to respond.

Staying Focused on Fundamentals

The first couple of replues hinted that it’s important to stay focused on the basics to be able to land almost any job in the future. After all, job titles change, but the fundamentals stay the same:

“Focus on the fundamentals and your learning skills. Be adaptable. Nobody here knows what the future holds. Anyone claiming they do either thinks too highly of themselves or is trying to sell you something.”

“Data structures, OOP, clean code, basics of Linux and networking would be a clean start.”

“This. And don’t skimp out on any of these! Networking knowledge has done just as much for my career as knowing how to write clean code and design patterns. Feel similarly about Linux.”

One coding recruiter also shared their knowledge based on their experience, saying that the most important basic is basically problem-solving and diligence:

“The real fundamental is being able to take a problem and translate it into working and maintainable solution represented by a computer system. What that means will vary based on the architecture you are working with. If your code readable and explainable, this is more important than performance most of the time. Is the solution elegant yet created in such a way that it is easy to expand at the natural points that make sense? It is testable with unit testing, meaning it’s setup in a way that supports mocking? Did you use the right data structure for the right problem(Array,Hashtable,Dictionary,etc) and can you explain why you used what? Just a couple of things I look for/ask new devs during code reviews.”

The Perspectives of Cyber Security, Distributed Systems, AI, and ML

Reddit Discusses Top Computer Science Fields Predicted to Grow in the Next Five Years

Nevertheless, there were users who recommended specific fields as well. The first career option that was said to be the most prospective ones were security and distributed systems:

“I’d suggest studying security and distributed systems. I know very few new grads who can design a complex system. I graduated in 2023, went to a state school. There are about 2000 graduates in CS at my school. About 1800 focused on ML/AI or graphic design. The last 200 of us focused on operating systems, distributed systems, or security. Everyone I know who studied those three has a job right now. Several of the people who studied the more low level stuff is working in ML right now and I personally got a couple offers for ML with very little experience in it.”

“Distributed systems. We seem to be pretty close to maxing out what we can do on a single system, to the point that high-end servers have a dozen or more processors in them. The cloud has also made spinning up 200 servers, having them crunch some numbers, and spinning them down practical. Efficiently distributing ML models is likely going to be big as well, since models are growing faster than the amount of memory we can put in a server.”

However, these were not the only fields mentioned to be successful in the future. Many mentioned that AI and Machine learning branches were also growing and would probably continue this trend in the following 5 years as well:

“ML/AI will definitely grow a lot more and be everywhere… but at the moment I think people getting into it vastly outnumber the actual demand. Just judging from the number of really great applicants we got from our last job ad for an ML role ;). But ofc nobody knows. There was a brief flash for graphics programmers with everyone wanting to build the metaverse. Then that completely crashed down again. I got almost no experience in that field and still got contacted by reality labs and friends during that phase.”

“Artificial Intelligence and Analytics Engineering are the two I’m hearing a lot about. Fortunately I got a job that serves as an intersection between the two despite a really bad market so I guess there’s some credibility to those claims.”

The General Vibes in CS Career

However, even though a lot of specialists in IT noted that current job prospects in the field do not look as bright as before, some said this to be an overstatement.

Others also second this thought saying that school is a place for exploration, so that you will be able to find yourself as a professional. After all, the first job after graduation may not be exactly what you were studying for or expected. That’s why it’s best that you at least find something that you are interested in and like doing.

A Glimpse Into The Future Scope of CS

The global technology market, currently valued at over USD 802.07 million in 2021, is on a trajectory to grow exponentially, potentially reaching USD 3168.13 million by 2027. This surge can be attributed to the rapid advancements in areas like big data analytics, cloud computing, and the Internet of Things (IoT). As a consequence, the U.S. Department of Labor projects a 14.6% growth in computer and information technology occupations from 2021 to 2031. With computer science graduates already commanding impressive salaries, averaging over $97,430 per year as of May 2021, the appeal of the field is undeniable.

Furthermore, the influence of computer science isn’t limited to the tech industry alone. Its ripple effect is being felt across sectors like healthcare, where computer scientists are innovating with wearable technologies and medical devices. In the financial realm, the introduction of blockchain and distributed ledger technologies promises secure and swift transactions.

Looking ahead, experts highlight several areas within computer science set for significant expansion. These include:

  • Robotics
  • Game Development
  • Virtual Reality
  • Cybersecurity
  • Data Analytics
  • Machine Learning
  • Quantum Computing
  • and DNA Computing.

Recent studies underscore the transformative potential of technologies such as Artificial Intelligence, IoT, Blockchain, and Cloud Computing. For instance, the rise of AI and Machine Learning has been pivotal in developing self-driving cars and enhancing predictive modeling. The Internet of Things, with its interconnected devices, is revolutionizing sectors from healthcare to agriculture, and its footprint is expected to further increase, with predictions of 75 billion connected devices by 2025.

As the boundaries of what’s possible continue to expand, the consensus is clear: the future of computer science is replete with opportunities and potential. For those considering a career in this dynamic field, the path forward is laden with promise, innovation, and the chance to shape the very fabric of our digital future.
