I was one month into my first full-time job, when I've (unknowingly of his rank) challenged the CTO in a technical discussion - in a public email exchange. Regardless of the outcome - I've been treated like an equal. This one short exchange has influenced not only the rest of my career, but my entire worldview.

I mean to some extent sure. But also you need to respect expertise and experience. So much of what we do is subjective, and neither side going to have hard data to support their arguments.

If it comes down to someone saying “I’ve been doing this for 30 years, I’ve shipped something very similar 5 times, and we ran into a problem with x each time”. Unless you have similar counter experience, you should probably just listen.

What happens in tech is you get a very specific kind of junior who wants to have HN comment arguments at work constantly and needs you to prove every single thing to them. I don’t know man it’s a style guide. There’s not going to be hard quantitative evidence to support why we said you shouldn’t reach for macros first.
