I think this blog fails to take into account that 2021 is not 2002. Computer Science is a much more formal/mainstream field of study now, and people don't operate "in a vacuum with no mentorship, guidance, or reference points.”

Some comments on the previous blog post raised important questions regarding minimum understanding/knowledge of technology one utilizes as part of their day job. And I would agree that indexing is a fundamental aspect while using relational databases.

But unfortunately this isn't very uncommon these days, way too often have I heard people in $bigco say, let's use X, everyone uses X without completely understanding the implications/drawbacks/benefits of that choice.

I don't see how 2002 was ever different in this from 2021 (except maybe for a stronger international dimension today).
