This poster's content is frequently clickbait for people who want to play "business" - i.e. garbage advice. Most advice is garbage (but that's an answer to a different question). "Generalist" and "Specialist" are too broad of terms. In my experience, people who claim to be "generalists" are simply on the verge of competence in a variety of areas. On the other hand, extreme "specialists" require a lot of support to get things done (e.g. machine learning PhDs with little experience in cloud computing, software engineering, etc.). So, somewhat paradoxically, the best "generalists" are "specialists" – people who are really successful in tech tend to be experts in one very valuable area, and competent in a few others. I can't recall anyone I'd consider "successful" not fitting that mold.
