In his 1969 novel, "The Age of the Pussyfoot", Pohl speculated about a society where everyone could access knowledge and the means to communicate with others through a small handheld device similar to a smartphone. Although he set the novel 500 years in the future, he noted in an afterword that it might be as few as fifty years away. A short story "Day Million" suggested that society in the year 2737 might be as alien to us as contemporary society would be to someone from ancient times.
