Pohl himself, in an afterword to [Age of the Pussyfoot], made the following statement about the world he foresaw:
"I do not really think it will be that long. Not five centuries. Perhaps not even five decades."
Forty years after the publication of the novel, most people of 2005 will recognise the functions of the Joymaker in the cellphone, laptop computer, and personal digital assistant. Only the medical capabilities are missing from devices carried by people in industrialized nations in the early 21st century. These devices, however usually have far more computing power than the Joymaker as conceived, and more even than the 1960s mainframe computers that provided the inspiration. Some of the actual social effects of portable communication and computing parallel those predicted in the novel.
Age of the Pussyfoot can be found in this bundle of books.
