I’d put more probability in the scenario where good $5 billion 1e27 FLOPs runs give mediocre results, so that more scaling remains feasible but lacks an expectation of success. With how expensive the larger experiments would be, it could take many years for someone to take another draw from the apocalypse deck. That alone adds maybe 2% for 10 years after 2026 or so, and there are other ways for AGI to start working.
