While some of the points in this post are valid most of this is just copy-paste non-sense stated in multiple articles. Of course "Scrum" cannot fix your problems if you have bad engineers who are happy to just "close" tickets or you have an organization where you do not know where to ask "who is knowledable about this business requirement". Scrum is a software delivery methodology which is ok in itself, it is not a silver bullet which will enable you to write great software which meets specification and runs for years without bugs, those things are completely tangential and require a specific set of skills.
