I've made my mistakes with rm - and tried to learn from them.  I see
no reason why we should default to rm -i .  The alias is easy enough
to set up if one needs it and one can still royally muck things up
with rm -rf or \rm.

I agree that it could create problems for those used to rm -i when
they encounter a pure rm machine but I think it is therefore better
that people learn to alias commands and the limitations and get
arounds of that alisasing.

In *nix based systems rm has always meant rm - deleting files does just that.
The KDE Desktop provides the option to keep this functionality or have
temporary trash can on the desktop.  However, you don't get the option
of a trashcan on the command line - unless you want to write your own
script for it.
