You can find AGI predictions, including Starcraft forecasts, in "When Will AI Exceed Human Performance? Evidence from AI Experts". Projects for having "all forecasts on AGI in one place" include ai.metaculus.com & foretold.io.
Looks like all of the "games"-oriented predictions that were supposed to happen in the first 25 years have already happened within 3.
edit: Misread the charts. It's more like the predictions within the first ~10 years have already been accomplished, plus or minus a few.
Is there a roadmap of major milestones AI researchers have to achieve through before AGI is here? I feel like this would be beneficial to update on AGI arrival timelines and adjust actions accordingly. Lately, a lot of things that can be classified as a milestone have been achieved -- GLUE benchmark, StarCraft II, DOTA 2 etc. Should we adjust our estimates on AGI arrival based on those or are they moving according to plan? It would be cool to have a place with all forecasts on AGI in one place.
