Should I Resign from My Full Professor Job to Work Fulltime on Cocalc?

In 2006, I moved from UCSD to a tenured Associate Professor position at the University of Washington (UW) mathematics department, primarily because my wife was a graduate student there, UW has strong research in number theory and algebraic geometry, and they have a good culture supporting undergraduate research. As a result, in addition to publishing dozens of research mathematics papers and some books, I also started spending a lot of my time writing software, and organizing Sage Days workshops. Of course, ICERM has turned out to be a fantastic institute, and it has hosted several workshops that support the development of open source math software.
