Which of these is actually ready?
Put two or three capabilities side by side and see exactly where the scores diverge — technical maturity, reliability, cost, autonomy or plain regulatory reality.
| Dimension | ||
|---|---|---|
| Technical capabilityweight 25% | 66 | 40 |
| Reliabilityweight 20% | 42 | 22 |
| Accessibilityweight 15% | 12 | 10 |
| Affordabilityweight 15% | 15 | 8 |
| Autonomyweight 10% | 45 | 20 |
| Regulatory & practical availabilityweight 15% | 12 | 12 |
| Typical cost | Trials are funded, not sold; consumer EEG headsets £200–£1,500 | Cloud quantum access from a few pounds per job; machines cost millions |
| Categories | Brain-Computer Interfaces, Health Tech | Future Computing |
| Verdict | For a small number of clinical trial participants, yes — and it is life-changing. Implanted interfaces let people with paralysis move cursors, type and control devices by intent. For everyone else, non-invasive consumer headsets remain crude: a few commands, lots of calibration. | No. Current machines are far too small and noisy to factor real keys. The genuine near-term risk is 'harvest now, decrypt later', which is why post-quantum cryptography migration is already underway in serious organisations. |
