The computer in your pocket is more powerful than many computers that once filled entire rooms. Today, technology is changing again—computers can generate content, robots can operate with greater independence and researchers can translate brain activity into computer commands.
Emerging computer technologies are innovations that are still developing or beginning to enter everyday use. Some are already available, while others may take years before becoming common.
Simple idea: Today’s experiment can become tomorrow’s everyday technology.
What Are Emerging Computer Technologies?
Emerging computer technologies are new or rapidly developing technologies that may change how we:
- Communicate
- Work and study
- Protect information
- Build machines
- Deliver healthcare
- Travel

Generative AI creates new content based on patterns learned from data.
It can generate:
- Text
- Images
- Audio
- Video
- Computer code
- Presentations
For example, a student might use generative AI to explain a difficult topic. A designer may use it to create early visual ideas.
However, AI-generated content may contain errors or invented information. Important answers should always be checked using reliable sources.
The NIST AI Risk Management Framework includes a dedicated generative AI profile to help organisations identify and manage risks related to these systems.
Agentic AI
Agentic AI describes systems that can plan and perform multiple connected actions to achieve a goal.
For example, an AI agent might:
- Read a meeting request.
- Check a calendar.
- Compare available times.
- Prepare a reply.
- Create a reminder.
These systems can save time, but they require clear permissions, security controls and human oversight.
Main AI concerns
- Incorrect information
- Bias
- Privacy
- Copyright
- Job changes
- Deepfakes
- Security misuse
- Lack of transparency
Remember: AI can produce an answer confidently without producing the correct answer.
2. Quantum Computing

Quantum computers use qubits, which behave according to quantum physics. This allows quantum systems to approach certain specialised problems differently from ordinary computers.
Possible uses
- Molecular simulation
- Medicine research
- Material discovery
- Complex optimisation
- Financial modelling
- Cryptography research
Simple example
Imagine trying to find the best route through an extremely complicated maze. A traditional computer may test possibilities using normal instructions. A quantum algorithm may represent and process aspects of the problem in a different way.
This does not mean quantum computers are faster for every task. They are not expected to replace normal laptops for writing documents, watching videos or browsing websites.
Current challenges
Quantum computers face problems such as:
- Qubit errors
- Environmental interference
- Difficult hardware requirements
- Complex programming
- Limited practical applications
- High operating costs
Post-Quantum Cryptography
Powerful future quantum computers could threaten some encryption methods used today. Post-quantum cryptography uses mathematical methods designed to resist attacks from both traditional and quantum computers.
In 2024, NIST released its first three final post-quantum cryptography standards.
This does not mean current quantum computers can suddenly break all modern encryption. It means organisations are preparing early because replacing cryptographic systems can take many years.
3. Edge Computing
Cloud computing normally sends data to a remote data centre for processing.
Edge computing processes data on or near the device where it is created.
Cloud approach
Device → Internet → Distant Data Centre → Result
Edge approach
Device → Nearby Processing → Fast Result
Examples
- Smart security cameras
- Factory sensors
- Self-driving systems
- Medical-monitoring devices
- Retail checkout systems
- Traffic-management systems
A smart camera using edge computing could analyse video locally and send only an important alert instead of uploading every second of footage.
NIST describes edge computing as processing data locally or in a nearby edge data centre to improve network performance and support connected devices.
Benefits
- Faster response
- Reduced internet usage
- Improved operation during limited connectivity
- Greater local control of data
- Lower delay
Challenges
- Device security
- Software updates

Different systems may be:
- Fully controlled by a person
- Remotely operated
- Partly automated
- Highly autonomous
Safety-critical robots require testing, monitoring and emergency controls.
7. Brain–Computer Interfaces
