Why would you go to all this trouble when you can just buy a cheap coffee maker (I use a Kalita Wave) and come out ahead in savings within a week? Coffee requires exactly two ingredients to make, one of which comes out of your tap. It's absurd to have it delivered by drone every day rather than just making it yourself. Is this the kind of thing that only sounds remotely reasonable to someone in the Bay Area?

Sometimes I just want a kick, and sometimes I want to really appreciate the flavor or get some sort of specialty drink. Most coffee I've had from coffee machines doesn't taste great, even with good beans, and if you want good espresso you need to spend a lot of money and effort... or you can get it from a place that does it for you.

But, yes, if you're looking purely for the caffeine and nothing else, a cheap coffee machine is the way to go.
