Infinity is a ridicilous statement. Even the work that wouldn't have been done before is now time away from work that needs to be done. At worst it's negative x.
Pretty sure this was one of those so-called “jokes” I have read about in a research paper once. American humor tends to rely on overstatement. This is contrast with British humor that more often builds on understatement.
It's a division by zero. We can change infinity to 'undefined'
