Yep! The only people I've ever known who were (literally) "on steroids" were uniformly and without exception psychopathic jerks. It's a stupid epithet, frequently used to describe the exact opposite of the sentiment it tries so pathetically to convey. Phrase ought to be retired.

More on topic: I'd love to see a mission or more focussed on exploring interstellar regions. I'll bet there's a whole lot more we'll learn there, even though I'll be long dead by the time it rolls around.
