> I am always surprised, though at this point I shouldn’t be, that there is always pushback against any attempts at improving the status quo when it comes to typing speeds on HN - as though the creator is attacking all of us with lower typing speeds personally…

I don't think it's a general attack because people are personally offended; most of the criticism right now seems to be that the headline claim is materially untrue. Rejecting snake oil is healthy and reasonable even if there's value to be found.

Edit: Perhaps more succinctly, people aren't pushing back against improvements, they're pushing back on deceptive claims.
