Subject: How longe before a wearable electronic translator is produced?

I see that we have programmes which will - more or less - transform the
spoken word into text on a PC.  OK, they aren't perfect, but they
seem to be improving.

I see that there are other programmes which will make a stab at
translating text from one language into another.  These are also a long
way (OK, a very long way) from perfect - but these are also getting
better.

Finally there are programmes which will convert text into speech.

Processors are getting faster, memory is getting smaller and wearable
computers are forecast.

So - how long before English teachers need to start worrying because 
everybody has a wearable translator?
