- @owlposting published a 3,800-word essay systematically assessing whether brain organoids are useful models for Alzheimer's research—one of the hardest diseases to study.
- Core argument: "all models are wrong but some are useful"—a model can be wrong in many ways yet useful in particular ones.
- The drug-discovery dilemma: whether a model is useful often can't be verified until years later, and even validated models are poorly understood.
- Takeaway: rather than cataloging every flaw, look for better approaches and see how they pan out. The author also announced a move to San Francisco.
