I think this is great advice for a beginner on their first project. Using React's localState for everything is a huge anti-pattern, but Redux adds cognitive overhead and boilerplate.
Later, when you do a real project, Redux makes debugging and state consistency about 10 times easier, especially on a team or coordinating between multiple teams.
