After decades of not only inventing, but using, promoting and educating about the advantages of a specialized notation for programming. Did Iverson start J because it was a distinctively better path than APL?
No. Of course not. After nearly thirty years of brilliantly creating and promoting his notation Iverson made a mistake. It would not be the first time in the history of technology this happened, and it won’t be the last.
J is fine, great, easier license, has a larger and more powerful set of primatives.
