I maintain and use an extensive collection of
personal shortcuts including scripts, aliases and
shell functions. I'm productive on systems where
I don't have those shortcuts available but I'm more
productive when I have them, so (since doing so is
usually trivial) I try to port them to any system
when I know I'll be using that system for any length
of time.
With BASH, aliases are generally deprecated in favor
of functions so I've honored that and haven't created
any new aliases in a while, though I do still use some
that I've had around forever.
It's always been obvious to me that it's bad practice
to name shortcuts the same as existing commands,
and I've therefore never had problems such as those
described earlier, like where "rm" unexpectedly
turns out to actually mean "rm" instead of "rm -i".
People who suffer thus are simply being punished
(justly) for their sins and would probably benefit
more from continued (but more prudent) use of shortcuts
than from abandoning them altogether. In other words,
one should not conclude that one's misuse of a facility
indicates that facility to be unfit for use. In other
other words, shortcuts don't "rm -rf /", people do...
