Everybody has opinions on grand challenges---bold tasks that capture the imagination of researchers and system builders---for AI. One of the earliest set of challenge goals was enunciated by Turing award winner and AAAI President, Raj Reddy, in 1988. I attempt to provide an accounting of the progress that has been made in the field, over the last three decades, towards those challenge goals. While some tasks such as the world-champion chess machine were accomplished in short order, many others remain incomplete. A new set of challenges for the current decade are also proposed, spanning the Health, Wealth and Wisdom spheres. Bridging the gap from narrow AI to general-purpose AI will be required to solve some of these challenges; teaming architectures in the service of humankind will also need to be emphasized. The mantra should be: Of the people, by the people
with machines
; for the people!
