Currently working on a programme of work for a huge client whose core system is still running the same COBOL spaghetti that was written in the 80s. The demand for COBOL developers to support or update these systems, and the compensation they get, is wild.
Have reviewed 16 year old code for a very well known company in the last week with this exact comment peppered throughout, alongside delightfully helpful comments like:
// do not delete or change this it just works
// TODO temporary fix added 12/09/11 to fix incident must be removed ASAP
// CAUTION this returns false here instead of true like it normally does, not sure why
// if true then matched to valid account not is true
