Emerging technologies are innovations that are rapidly developing and expected to significantly change industries and daily life. In IT, the leading examples include artificial intelligence, machine learning, natural language processing, blockchain, Web 3.0, the Internet of Things, augmented and virtual reality, cloud computing and big data analytics — all covered on this page.

Artificial intelligence is the broad goal of building systems that perform tasks requiring human-like intelligence. Machine learning is a subset of AI in which systems learn patterns from data rather than following hand-written rules. Natural language processing and deep learning are further specialisations within this family.

Web 3.0 is the proposed next phase of the internet built on decentralisation, blockchain and token-based economics, where users own their data and digital identity rather than relying on centralised platforms. It contrasts with Web 2.0, the current platform-driven, social web.

For most learners, AI and machine learning offer the broadest career opportunities and underpin many other technologies, so they are a strong starting point. Cloud computing and big data are also high-demand foundations — they’re marked as Key topics on this page for that reason.
