I really, really quickly skimmed the comments and title then mentally chose the wrong order of "friend/fast/fast/friend".

The flaw in this particular part of the HN mindset is looking at a set of information and thinking you can instantly identify the other person's problem (or that there is one!) and explain/solve it using what you already know.

I think other people might recognize this in their own thinking sometimes too!

I think that's fine, as long as you learn to back down and reconsider the moment someone presents competing information.
