Must Learn Technologies In 2021

With the pandemic still ongoing and most of us working from home, 2021 is a great opportunity for you to learn new technologies.

Below is a list of top technologies that you can learn to keep up with the trends.

Blockchain Technology

Blockchain is the technology behind cryptocurrency. However, blockchain has more to offer. We are currently seeing blockchain begin to be used in transactions as it eliminates the need for an intermediary and improves security.

The blockchain market is expected to experience a compounded growth rate of 82.4% from 2021 to get to 3.67 billion by 2028

To get started with blockchain, you need to be familiar with programming languages, data structures, fundamentals of OOPS, flat and relational databases, web app development, and networking.

Quantum computing

is a form of computing that takes advantage of quantum mechanisms like superposition and quantum entanglement. In the health sector, quantum computing can be used to develop potential vaccines due to its ability to query, monitor, analyze and act on data regardless of the source.

In banking and finance, quantum computing can be used to manage risks and detect fraud. Quantum computers are thousands of times faster than normal computers which have seen their adaptation by companies like Microsoft and Google.

To get started with quantum computing, you would need background knowledge on quantum mechanics, linear algebra, information theory, probability, and Machine Learning.

Internet of Things(IoT)

In 2021, IoT would evolve into the intelligence of things as more and more devices become Artificial Intelligence (AI) enabled. IoT hardware and software are expected to see high growth due to economic stimulus, remote access demand, and industry dynamics.

Companies like Huawei, IBM, and Cisco are working to develop IoT apps. It is expected that there will be 13.8 billion IoT devices by 2021 and 30.9 billion by 2025.

To get started with IoT you need to have experience with information security, networking, business intelligence tools, UX/UI designs, and AI and machine learning.


cybersecurity has and will become a growing trend due to the need to protect small organizations from cyber attacks, protecting the identities and devices of remote workers, protecting confidential patient records, and protecting smart supply chains, etc.

The need to protect against cyberattacks will lead to a lot of emphasis on cybersecurity. According to Cyber Crimes Magazine, it is expected that 6 trillion dollars will be spent on cybersecurity globally.

To get started with cybersecurity, you will need experience in IT(Information Technology) fundamentals, cloud security, coding skills, and malware analysis.

5G network

3G and 4G networks have enabled us to browse the internet, increase bandwidth for streaming and use data-driven services. Similarly, 5G aims to revolutionize the industry by enabling technology that runs on AR and VR alongside cloud-based gaming services like Google stadia.

5G will be used in factories, High Definition (HD) cameras to improve safety and traffic management. Companies like Nokia and Apple are working to create 5G applications. 5G applications are expected to officially launch worldwide in 2021. 

 Where do you begin?

  1. Start today. Start where you are. Whatever technical skills spark your interest, be it data science, cloud computing, AI. e.t.c, learn it and learn it well.
  2. Don’t be afraid to start. Remember that the greatest barrier to learning something new is not intellectual, it is emotional. So do not let the fear of failure hold you back.
  3. Here is a link to the 20-hour Rule on how to learn anything, as a reminder that you should start today.
