I teach so the average student is my benchmark. Please do not
misunderstand. While some may be lazy, but the average CS undergrad is
not stupid but quite intelligent. They just do not like wasting time
with setups and I sympathize with that. Batteries included is the

Don't shoot the messenger please.
You can dismiss or address the problem. Anyway... undergrads do care
because they will take 4 years to grade and they do not want to come
out with obsolete skills. Our undergrads learn Python, Ruby, Java,
their own (Scala and Clojure are popular). They all agree multi-core
is the future and whichever language can deal with them better is the
As masklinn says, the difference between garbage collection and
reference counting is more than an implementation issue.
