TeX is not a bug-free software

> For the sake of illustration, I'll be using LaTeX. I know they are not the same, but since LaTeX is essentially a bunch of macros on top of TeX, and error messages come from the TeX processor (plus almost no-one uses plain TeX), I think my point will still stand.

That assumption is wrong. TeX has great error messages.

It simply cannot do much when you obscure everything with layers upon layers of general macros, like LaTeX.

But the normal plain TeX usage yields really good error messages.

And, of course, the article’s title is unsupported clickbait.
