In 2020, mobile phones are becoming available with the option of texting by thought power alone.
A sensor-mounted headset is worn by the user. This contains brain-machine interface technology, which analyses brain waves and converts them into digital signals.
Some of the higher end models feature glasses or visors, with displays built into the lenses. This allows completely hands-free texting, effectively creating a form of electronic telepathy. The process is rather slow at this stage - requiring a high degree of concentration - but advances in the coming decades will revolutionise communication.
