Points of discussion:
Will typing be necessary in the near future?
When will technology make it possible for everything to be spoken?
Is it a requirement TODAY?
What are the benefits of being a touch typist?
Is it the right tool for everyone?
What do I think:
The right tool for the right purpose at the right time for the right person. Let me explain...
A dyslexic person may require spoken software that does the typing for me through voice recognition (this being said, I myself am dyslexic and so are both of my sons and many of many extended family - we are all touch typist - it is actually a skill we have mastered somewhat easily and helps us all 'get it right' - especially if copy typing - spelling is not too big a deal as we use spell check software). Other dyslexics however struggle terribly to get their ideas written in any form.
An interesting point was made in relation to historical tools. In the 'olden days' lol, children were taught how to clean the end of their 'stick' before re-inking in a well... we've moved from pens to typewriters and now voice is becoming common place - in the future, are kids going say "what? you used to write? with a thing in your fingers? there was a what attached to your device?"
I believe we should be teaching the tools of TODAY, cause they need it TODAY and when it is no longer needed, adapt and teach what is required then.
