It’s fine if you’re bugged by the writing or argument style, but there is plenty of solid science on the side-effects of caffeine. It’s interesting that you criticize the author for being unscientific and then share a hyperbolic twitter anecdote and cast unsupported FUD on the science. The good science that we have always acknowledges that people respond differently, and yet we usually clump into a normal-ish distribution where the vast majority of people have very similar experiences, and we can quantify how similar and how often, and sometimes why there are deviations. Failing to acknowledge the similarities is as bad as failing to acknowledge the differences, scientifically speaking.
