And before anyone says so, no it has nothing to do with the supposed lessened attention span smartphones have caused. I'm not wasting 15 minutes of my life reading about social media recommendation algorithms [1] when not even a single paragraph is dedicated to at least some rudimentary technical explanation behind them.
Same goes for 30-minute YouTube videos attempting to maximize monetization for subjects whose explanation in less than 10 minutes for an average intelligence person is adequate.
Here's also a recent example of ideal, imo, technical writing that is sadly getting more scarce:
Recipes tell you how their great grandmother moved to the Americas and made the first apple pie ever. And then detail the entire history of apples and how to make the entire recipe. And then, 70% of the way down the page, right before the comment section, is what you wanted at first glance: what’s in this pie, and how long will it take me to make?
It’s everywhere.
