Are MOOCs putting teaching professors out of a job?
No. From The Kernel, 2015:


  Just a few short years after promising higher education for anyone
  with an Internet connection, MOOCs have scaled back their ambitions,
  content to become job training for the tech sector and for students
  who already have college degrees.
  
  At what was arguably the peak of the hype about massive open online
  courses, the New York Times crowned 2012 as “The Year of the MOOC.”
  That was the year computer science professor Sebastian Thrun announced
  that, after an experiment teaching an online course that attracted
  100,000 enrollees, he could no longer teach at Stanford; he was
  founding an online education startup, Udacity. That same year, his
  colleagues in the department, Andrew Ng and Daphne Koller, founded a
  competing MOOC startup, Coursera. Harvard and MIT also launched their
  own (nonprofit) MOOC initiative, edX. And universities around the
  world scrambled to partner with one or more of these organizations,
  amidst claims from investors, entrepreneurs, and pundits that MOOCs
  were poised to bring about the end of the university as we know it.
  
  “In 50 years,” Thrun told Wired, “there will be only 10 institutions
  in the world delivering higher education and Udacity has a shot at
  being one of them.”...
  
  Yet despite these well-rehearsed and triumphant stories of MOOCs’
  global outreach, the notion that MOOCs could provide higher education
  to everyone quickly proved flawed. The success stories were the
  exception, rather than the rule. MOOCs were lambasted for having a
  high dropout rate; the average completion rate still hovers around 15
  percent, a level that would be unacceptable for a traditional
  face-to-face college class. And when the demographics of “successful”
  MOOC students were scrutinized in one University of Pennsylvania
  study, it was discovered that 80 percent already had college degrees.
  Rather than providing opportunities for the educational “have-nots,”
  MOOCs seem just as likely to further the opportunities of the
  educational “have-alreadys.”...
  
  Thrun has abandoned his prediction that there will only be 10
  universities in the future. What he’s retained is a story in which the
  only reason for post-secondary education is to fulfill the needs of
  employers—something colleges, he claims, do not do well.
