This is bad in two ways:
1) The people taking these courses do not learn much for the effort and time they spend. Also it gives them illusion that they know enough as they take course from big university.
2) Industry is already so confused in hiring, they hire by name. So even you take these courses and study in depth on your own you can't get hired. Someone more qualified can not get hired just because they can't pay 100k to get a degree in machine learning from one of these big university.
This is really a bad trend and we should spend time on real courses. Everyone knows that TV series are waste of time, these courses are like TV series.
Stop watching them.
Even if you believe it's pointless it's pretty clear it's no something everyone else "knows".
