5️⃣ 🚀 Digital Entrepreneurship (Create Your Own Company)
With computer science knowledge you can create a startup without the need for technical partners. Great companies like Facebook, Google, Amazon and WhatsApp were born from programmer founders.
6️⃣ 🔄 Versatility: You Work in Any Sector
You don’t need to work for a “technology company”. Computer scientists work in banks, hospitals, agriculture, fashion, sports, education, government… All sectors need technology.
7️⃣ 📈 Accelerated Professional Growth
In computer science, you can go from junior to senior in 2-3 years. In other professions, that promotion takes 5-10 years. Certifications (AWS, Cisco, CompTIA, Microsoft) accelerate your career.
8️⃣ 🌐 Global and Social Impact
You can create applications that improve the lives of millions. For example, medical applications, free educational software or tools for NGOs. Your code can change the world.
9️⃣ 🎓 Continuous Learning and No Ceiling
Technology advances every day: AI, virtual reality, blockchain, quantum computing. You will never get bored. There is always something new to learn, and most resources are free (YouTube, freeCodeCamp, Coursera, edX).
🔟 💼 Guaranteed Employment (Almost Zero Unemployment Rate)
According to the OECD (Organisation for Economic Co-operation and Development), the unemployment rate in the technology sector is 1.8%, compared to the general average of 6.5% in 2025. If you know how to program, secure job.

❓ 5. 10 FAQS (Frequently Asked Questions about Studying Computer Science)
- Do I need to be a math genius to study computer science? No. Logic and basic arithmetic are needed. Advanced mathematics (calculus, linear algebra) is used in AI and data science, but not in web or mobile development.
- Can I learn computer science on my own without going to university? Yes. Thousands of programmers are self-taught (bootcamps, YouTube, official documentation). University provides structure and a degree, but it’s not mandatory.
- How long does it take to learn programming from scratch? In 6 months of daily study (2-3 hours) you can get a junior job. In 2 years you are competent. In 5 years, expert.
- What programming language should I learn first? Python (due to its simple syntax and versatility) or JavaScript (because it works in any browser).
- Is there an age limit to study computer science? No. People aged 40, 50 or 60 reinvent themselves in technology. Previous experience in other fields is an added value.
- Do women have opportunities in computer science? Yes, many. The sector actively seeks gender diversity. Organizations like Women Who Code, Girls Who Code and Google’s Women Techmakers offer scholarships and mentorships.
- What certifications are most valued? CompTIA A+ (support), CompTIA Security+ (cybersecurity), AWS Cloud Practitioner (cloud), Cisco CCNA (networks), Microsoft Azure Fundamentals.
- Can I work abroad from my country? Yes. Platforms like Upwork, Toptal, RemoteOK and We Work Remotely connect professionals from any country with global companies.
- What is better: university degree, bootcamp or self-taught? It depends on your context: degree (structure, degree, networking), bootcamp (intensive, practical, expensive), self-taught (free, flexible, requires discipline).
- Will artificial intelligence replace programmers? No. AI (like ChatGPT) is a help tool, not a substitute. Programmers will be more productive, but they are still necessary to design, review and maintain complex systems.
