Coffee already has vastly superior alternatives if all you want is productive tunnel-vision. But, of course, there are a lot of other nice things about coffee like how it's engrained in our culture, socially acceptable, something to grab a cup of on a date, its aroma as you sit tired in an airport terminal, when all you want is a cheap narcotic buzz with minimal come-down, etc.
