Yes, that's how I explained it myself as well - a lot of people have life and jobs they hate, they're overstressed and here is a cheap and socially approved (pressured even) way to deal with it.

I had a programming as a hobby since age of 6 and non-controlling parents, so I was good.

Caffeine I don't care much. I love culture of coffee, and enjoy good coffee. The latest metastudy I read on coffee concluded that there is no detrimental effects, unless excessive consumption or special conditions. Seems safe to me. I also tried 3 months off the coffee completely and it was incredibly easy switch - no issues at all.
