"If you’re a self-taught engineer or bootcamp grad, you owe it to yourself to learn computer science. Thankfully, you can give yourself a world-class CS education without investing years and a small fortune in a degree program"
.. They then go on to list various categories of information and skills in each high-level topic.
First of all, it implies that someone who is "self-taught" may be basically equivalent to someone who just finished a bootcamp. That is ludicrous. A "self-taught engineer" might have been programming and studying computer science topics for 30+ years, whereas someone who only attended a bootcamp may have only had four months of training or something.
Secondly, it implies that self-taught engineers do not have computer science knowledge or skills. This is also a ridiculous belief.
Now, examining the specific list of topics.
'Programming. Don’t be the person who “never quite understood” something like recursion.' -- This implies that self-taught engineers do not understand recursion. If someone calls himself a "self-taught engineer" or "bootcamp graduate" and does not understand recursion, then he should not call himself an engineer and/or should not have been allowed to pass the bootcamp. Again, this description shows that the creator of the website assumes that "self taught engineers" and "bootcamp graduates" in fact have virtually no useful skills and knowledge. Its asinine and quite insulting.
'Algorithms and Data Structures. If you don’t know how to use ubiquitous data structures like stacks, queues, trees, and graphs, you won’t be able to solve challenging problems.' The ridiculous implication here is that self-taught engineers don't know what a stack, queue, or tree is.
Another general criticism I have is that the creator of this website seems to think that watching videos and reading books is a good way to learn. Unless the books or videos have exercises (and the book recommendation I saw did not have exercises), that is horrible advice and a huge waste of time. If you are just looking for something like a survey or reference, passively watching the videos or reading the books could be useful. However, there is nothing so special about these books or topics that they cannot be learned about from many different websites.
