> Writing is one of those neat thing we keep forever.
Hah! You must be a young 'un. My handwriting has deteriorated over the years, from a pretty bad start. And "neat" would be an eccentric description of my style.
...and RSI, and arthritis of the knuckles. I don't relish the prospect of 3 days of handwriting. And I've never had pretty handwriting; all that would "come back" would be the ability to scribble fast. The ability to write nicely would never come back, because it was never there in the first place.
I think over 18 years of education it's reasonable to teach kids both forms of writing.
There is no lack of curriculum space.
Most things we learn we forget. Writing is one of those neat thing we keep forever.
