It’s a beginners book filled with a mix of bad and good advice, which takes considerable experience to separate the two. Those who can point out all the bad advice already don’t need the book, and newer developers will pick up absolutely atrocious coding advice. There’s simply better books that target beginners better, like The Pragmatic Programmer.

So when you are on-boarding junior devs that have bought into the clean code/SOLID dogma, you’re spending several months beating all their terrible coding habits out of them.
