And here's the problem with Wikipedia - while technically darker roasted coffee doesn't have more caffeine by volume than lighter roasts...technically the way coffee is brewed properly is by weight, and darker grounds are often used for things like espresso, which requires a much finer grind. So the same volume of dark grounds will technically have more coffee grounds than a lighter roast used for drip or pour-over.
Lots of detail is obfuscated when things are summarized. Sometimes those details matter.
Also, it seems a lot if this doesn't address the facetious or hyperbolic angle of these statements (though several do).
Again, sometimes this change in level (or direction) of focus fundamentally changes what something means.
I like how everyone else is saying, "Oh sweet! Look at this thing I just learned today!"
And then this guy is over here with "Well aktually espresso is totally different from drip coffee and so this totally unrelated thing Wikipedia was saying is all wrong I'm so smart."
I think Lemmy needs some kind of daily "smart person contest" to draw off the energy that otherwise gets spent on trying to find someone to prove wrong in the comments at the expense of everything else. Lord knows, I need one of those too.
