In my opinion, yes we should still be taught handwriting. Joint-writing (or cursive in US terms) is debatable really, because it's unnecessary and tends to aid how illegible people's hand-writing can be. But writing in general is something that should always be taught. It's a basic skill. Although for the majority of the time it isn't needed, if today someone told me that they didn't know how to write I would consider them partly illiterate.
I live in Ireland, where we still are taught Irish as a compulsory subject, unless you have special exemption, you cannot get into University without it as a general rule, along with Maths and English. Do we need Irish? Of course not. It's a national pride thing to bring it down to it's basic level. Somewhat similar to the chinese case made in the article, the national pride of being able to write the symbols of the language.
But, to wrap up an unnecessarily long comment, it should still be taught as there isn't a strong enough reason to not learn it. Not yet, at least.
