• Hacker News1We should be more ambitious with the software we buildAI advances let individual builders tackle ambitious software once deemed too costly, and a well-tested rewrite even uncovered real bugs. Projects that once took years now take hours, though newer models still aren't a complete solution.Ambition and real-world limits of AI-assisted coding:Commenters debate whether AI enables ambitious new products or mainly speeds up familiar work. Many note that AI makes MVPs easy but struggles with product tradeoffs, maintainability, and novel ideas, and that good ideas and human judgment remain the bottleneck.Code quality, review, and hidden costs of AI output:Users report AI producing fragile, overfit, or poorly reasoned code, such as string-matching logs or misused dict lookups. Review processes and coordination overhead can erase productivity gains unless engineers understand what they ship.Software quality and productivity beyond AI hype:Commenters lament poor-quality consumer and hardware software, and argue that good ideas, user testing, and standards matter more than raw speed. Some see AI enabling reverse engineering and personal tools, while others doubt it changes outcomes much.
• Reddit science1Magic mushroom compound psilocybin grows new brain connections within 24 hours and repairs circuits damaged by chronic stress in mice. Scientists found the brain rewiring runs on a different pathway than the trip itself, opening the door to fast-acting depression drugs without the hallucinations.Ketamine as an alternative:Commenters debated ketamine's role in depression treatment versus psilocybin, citing its existing clinical use, misdosing and abuse risks, and IV administration under specialist supervision.Psychedelic effects without hallucinations:Users questioned whether benefits can be separated from the hallucinogenic experience, arguing visual disruption helps reconfigure fixed mental models, while others suggested drugs like Ariadne as alternatives.Legal barriers and access:Commenters said expensive private treatment and restrictive laws push people toward illicit sources, though Oregon, Colorado, and New Mexico now offer psilocybin treatment, a model other states could follow.
