1. Artificial Intelligence Everywhere
Artificial intelligence is likely to become a normal part of many computer systems rather than a separate application.
AI may be built into:
- Operating systems
- Smartphones
- Vehicles
- Medical devices
- Search tools
- Office software
- Security systems
- Household appliances
- Industrial machines
Instead of opening a separate AI tool, users may interact with AI throughout their normal work.
Generative AI
Generative AI creates content such as:
- Text
- Images
- Audio
- Video
- Computer code
- 3D models
Future generative systems may become better at combining different types of input.
For example, a user might:
- Show the AI a photograph of a broken device.
- Describe the problem using speech.
- Upload the instruction manual.
- Receive an illustrated repair explanation.
Important outputs will still require verification.
AI Agents
AI agents are designed to perform connected actions toward a goal.
A future work assistant might:
- Read a project request
- Search authorised files
- Create a task list
- Check a calendar
- Prepare a draft
- Ask for approval
- Send the final version
Agents can save time, but they require:
- Limited permissions
- Human approval
- Activity logs
- Spending controls
- Security monitoring
- Reliable error handling
An intelligent system should not receive unlimited control simply because automation is convenient.
On-Device AI
Some AI processing is moving from distant cloud data centres to local devices.
On-device AI may provide:
- Faster response
- Reduced internet dependency
- Greater privacy
- Lower network usage
- Offline features
A phone may process speech, images or personal information locally instead of uploading everything to a cloud server.
Large AI tasks will still often require cloud or high-performance computing.
2. Quantum Computing
Traditional computers use bits that represent either 0 or 1.
Quantum computers use qubits, which behave according to quantum physics.
Quantum computing may provide new methods for certain specialised problems involving:
- Molecular simulation
- Material discovery
- Optimisation
- Cryptography research
- Scientific modelling
Quantum computers are not expected to replace normal laptops for browsing, documents or video streaming.
Hybrid Quantum Computing
Future systems may combine classical and quantum computers.
A normal computer may:
- Prepare the data.
- Send a specialised problem to a quantum processor.
- Receive the result.
- Continue normal processing.
This hybrid model is more realistic than every person owning a quantum laptop.
Quantum Challenges
Quantum systems still face:
- Qubit errors
- Environmental interference
- Difficult cooling requirements
- Complex programming
- High cost
- Limited practical advantage
- Difficult scaling
Quantum computing is important, but predictions about exact breakthroughs should be treated carefully.
3. Post-Quantum Cybersecurity
Powerful future quantum computers could threaten some encryption methods used today.
Post-quantum cryptography uses mathematical methods designed to resist attacks from classical and quantum computers.
NIST has released three principal post-quantum cryptography standards that can be implemented now, while additional algorithms continue to be evaluated.
This is important because organisations may need years to:
- Find old encryption
- Update software
- Replace equipment
- Test compatibility
- Protect archived data
Future security begins before the future threat fully arrives.
4. Exascale and High-Performance Computing
A supercomputer combines enormous processing power to solve problems that ordinary computers cannot handle efficiently.
Exascale systems can perform more than operations per second—one quintillion operations.
The US Department of Energy explains that exascale computing can support advanced work involving:
- Climate models
- New materials
- Energy research
- Nanoscience
- Fusion research
- Medicine
- Scientific simulation
Exascale computers and quantum computers are different. They may complement each other rather than directly compete.
5. Edge Computing
Cloud computing sends data to remote data centres.
Edge computing processes data closer to where it is created.

Edge approach
Device → Nearby Processing → Fast Result
Edge computing may become increasingly important for:
- Factory robots
- Smart vehicles
- Security cameras
- Health monitors
- Traffic systems
- Agricultural sensors
- Augmented reality
Example
A safety camera detects a worker standing too close to dangerous machinery.
Waiting for a distant cloud server may introduce unnecessary delay. An edge device can analyse the video locally and stop the machine more quickly.
Many future systems will combine cloud and edge computing.
6. Internet of Things
The Internet of Things connects physical devices containing sensors, software and network features.
Future IoT systems may connect:

The challenge is that every connected device can become a security and privacy risk.
7. 6G and Future Networks
6G is the next generation of mobile-network technology being developed after 5G.
The International Telecommunication Union calls it IMT-2030. In 2026, ITU experts completed technical performance requirements used to evaluate future 6G radio-interface proposals.
The ITU IMT-2030 process is inviting candidate technologies during a future evaluation period. This means 6G remains in research and standardisation rather than being an ordinary consumer service today.
Possible future uses include:
- Advanced industrial automation
- Connected transport
- Immersive communication
- Large sensor networks

It may combine:
- Virtual reality
- Augmented reality
- Mixed reality
- Hand tracking
- Eye tracking

The W3C WebXR Device API supports browser interaction with virtual and augmented reality hardware.
Future spatial systems must address physical safety, accessibility and privacy because headsets may collect detailed movement and environmental data.
9. Brain–Computer Interfaces
A brain–computer interface, or BCI, connects brain signals with an external device.
A basic process is:
Brain Signal → Sensor → Computer Analysis → Device Command
Possible uses include:
- Communication assistance
- Cursor control
- Rehabilitation
- Prosthetic control
- Brain research
In 2025, NIH reported research in which a brain–computer interface translated brain activity into audible words to support communication after paralysis.
This remains a specialised medical and research field.

A future system may contain:
- General-purpose CPU
- Graphics processor
- AI accelerator
- Security processor

Security must be designed into future systems from the beginning.
18. Privacy-Preserving Computing
Future systems need ways to analyse information without unnecessarily exposing the original data.
Developing approaches include:
- Federated learning
- Differential privacy
- Secure multiparty computation
- Homomorphic encryption
- Trusted execution environments
Federated learning example
Several phones help improve a shared model without directly uploading every user’s raw data to one location.
These methods can reduce some privacy risks but do not automatically make a system completely private.
19. Sustainable and Green Computing
Future computing systems must consider energy, cooling, materials and electronic waste.
The International Energy Agency projects global data-centre electricity consumption to reach approximately 945 TWh by 2030 in its base case.
Read the IEA Energy and AI analysis.
