The capabilities of IBM's Mainframe Operating Systems of the early 1970s were limited . Lack of Spooling system was one of the limitations. Group of four expert Programmers offered IBM a Spooling System which could be integrated into IBM's Operating System. IBM was ready to pay for that Spooling System because it would enhance significantly the Multi Tasking capabilities. IBM's managers asked them: How long it will take to code the Spooling System and integrate it with the Operating System? The answer was: 6 months. How long it will take if we will add 70 programmers to your team? The answer was: 2 years. Only the 4 experts participated in writing HASP the first Spooling System in IBM Mainframe Operating System. Later versions evolved from HASP were Jes2 and Jes3. Lessons Learned on AI Coding Code created by AI probably is in the level of code created by the 70 programmers mentioned in the previous paragraph. The code built by the four experts is a lot better....
