The M1 is a poor example to lead into an otherwise great post. The big leap with the M1 is the power efficiency. No amount of optimized code is going to keep Intel from running hot: installing Win95 on a latest-gen Intel laptop would be whip-fast, but wouldn't result in all-day battery life. An opinionated and lengthy intro like that serves as an invitation for readers to bail out before they get to the meat of the post: which would be a pity in this case, because it's worth reading.
