No you don't understand, this person writes quality code in an intellectually honest way because they use machines in a very specific way, just enough but not too much. Everyone else is just slinging shitcode. Good luck finding someone as good as this random person online you've never heard of!
I don't mean to attack this person specifically but it's a frankly pretty bad mindset that is far too prevalent in our profession - the way I do things in the Right Way, I write Good Code, very few other people write Good Code, and because I do things the way they were done 5, 10, 25 years ago means that my way is better than yours.
