WHY DO AGI TIMELINES VARY SO WIDELY?

Summary from the TLDR AI newsletter

Many lab CEOs predict 2-5 years until AGI, while outside experts forecast decades or argue AGI is impossible with the current approach. Short-timeline advocates point to saturating benchmarks, AI task completion doubling every 7 months, and the potential for automated AI research to trigger an intelligence explosion. Long-timeline skeptics counter that benchmarks only measure easily defined tasks, that Moravec's Paradox suggests we've automated the "easy" cognitive work first, and that raw intelligence alone doesn't drive scientific breakthroughs.
