I'm going to add my anecdata in here -- mid 20s, and I do not consume caffeine. I don't drink coffee, tea, or soda regularly. Nor do I drink energy drinks. No caffeine isn't a new thing, I've just never really drank it. I haven't tried drinking caffeine regularly enough that I can tell whether there's a productivity boost to taking it. I'd like to say I'm pretty productive -- previous job was ranking me in top review buckets for my pay grade(s) for multiple years. One thing I've noticed is that I'm a morning person, my best hours are 8am-12pm. Most of my coworkers (coffee drinkers) are afternoon people. Not sure if that's a trend or just programmer biases. I have noticed that pretty much all of my caffeine consuming co-workers need to have their coffee before I can ask them anything mildly complex. That could just be ritualistic behavior (get into work, make coffee, don't think about work until then), but could also be caffeine dependency.
