In this note I’ll summarize the bio-anchors report, describe my initial reactions to it, and take a closer look at two disagreements that I have with background assumptions used by (readers of) the report. This report attempts to forecast the year when the amount of compute required to train a transformative AI (TAI) model will first become available, as the year when a forecast for the amount of compute required to train TAI in a given year will intersect a forecast for the amount of compute that will be available for a training run of a single project in a given year.Original article:https://docs.google.com/document/d/1_GqOrCo29qKly1z48-mR86IV7TUDfzaEXxD3lGFQ8Wk/edit#Narrated for the Effective Altruism Forum by TYPE III AUDIO.Share feedback on this narration.
