I have come across students who have very different goals:
Collins's class covers item (3) in more detail than my class.
Both the 2012 Manning and Jurafsky class on Coursera and my class cover (1) in detail.
I also spend some time on (2) and (3) but not on (4) or (5), which are more research-oriented.
Students interested in (4) or (5) are encouraged to pursue a PhD and/or work for a company that does R&D work.
