It's by Stephen Diehl, and as much as this community thinks it's above arguments from authority/ad hominem attacks, it will still favor reputable sources as a means of filtering. So ignoring an argument from him will hardly be sufficient.
Stephen is bombastic in all the worst ways, while insulting and looking down on other engineers. I’m willing to look past Stephen being the author and give the general story of Bitcoin power consumption a fair shake despite it (and a clear-minded assessment suggests it’s a total non-story), but Stephen being the author absolutely does not help with credibility.
