AI Leaps Five Years in Six Months

Irreversible Space Settlement: The Overlooked Existential Threat

What's the most underrated existential risk? Irreversible space settlement. 1. AI could make space settlement possible in our lifetimes: 1 minute of solar energy is enough to accelerate 10 billion 1kg self-replicating AI probes to 99% the speed of light.

Evidence-Based Medicine Once Labeled Dangerous Innovation by Doctors

Obviously you want "evidence-based medicine", but the term was only coined in 1991. Doctors called it a "dangerous innovation", preferring to rely on their judgement over trials.

Robots Likely in Homes by 2030, Scarce Industrially

Forecasters think there's a ~60% chance that by 2030 "robots exist that can navigate homes and perform basic tasks" or better, but only 17 million are used industrially by 2040. Seems insane. https://t.co/SgVhz1xW6C
