I think the article has an implied context of "for work." Implementing data structures and algorithms is a great way to learn about them and to get better at programming. But in the context of work, where I need to get stuff done, I'm not going to implement a low level algorithm if I don't need to - I'm looking for a pre-built solution in the standard library, or heading to a search engine to find a third party library. That's not to say some training time at work isn't a good idea, but it'd be silly for a person's business to fail because they got caught up implementing all of their low level data structures for coding practice.
