  10. Language Work 8

  11. Language work 8 • I think it’s possible that ATM machines will use iris recognition rather than PIN numbers. • I think it’s probable that people will vote in elections online. • It’s very unlikely that taxis will be robot controlled. • It’s just possible that TV journalists will be able to transmit what they see by using sensors in their optic nerves.

  12. Language work 8 • It’s unlikely that there will be more robots than people in developed countries. • It’s very likely that most computers will be voice-controlled. • Mobile phones may replace computers as the commonest way to access the Internet. • English might no longer be the commonest language for websites. • Email probably will be replaced by a voice-based system. • Computers will certainly become more powerful.
