Our muscles will atrophy as we climb the Kardashev Scale
Premise and Overall Reaction
- Many commenters find the “muscles will atrophy as we climb the Kardashev scale” premise simplistic or “silly.”
- Core criticism: it linearly extrapolates from current trends, ignoring biology, culture, and technology co-evolving in messy ways.
- Others engage with it as a fun thought experiment about trade‑offs between efficiency, embodiment, and human desire.
Strength: Past vs Present
- Several argue pre‑modern laborers were often smaller, weaker, and malnourished; heavy work coexisted with starvation, parasites, and disease.
- Modern people can be stronger due to nutrition, medicine, and deliberate strength training, even if average daily activity is lower.
- Others note the obesity epidemic and declining fitness (e.g., military recruitment issues) as counter‑evidence of general robustness.
Biotech, Drugs, and “Exercise in a Pill”
- Multiple threads discuss GLP‑1 agonists, exercise mimetic drugs, myostatin inhibitors, and testosterone/TRT.
- Some are optimistic that exercise and atrophy will be solved pharmacologically or genetically long before interstellar travel.
- Others are skeptical: long‑term side effects, systemic impacts (heart, tendons, mood, fertility), and “no free lunch” concerns are emphasized.
- Distinction is made between supraphysiologic bodybuilding doses and therapeutic replacement levels.
Body, Mind, and Future Civilizations
- Strong theme: physical fitness and mental health/cognition are tightly linked; a “brain in a jar” future could be psychologically harmful.
- Several expect biological or cyborg futures (genetic upgrades, exosuits, engineered bodies) rather than pure uploads.
- Others speculate about branching human lineages (biological, robotic, uploaded), off‑world colonies, and civilizational splintering.
- Some criticize the Kardashev scale itself as flashy but not very useful; others see it as sci‑fi jargon or “in‑group signaling.”
Culture, Choice, and Desire
- Many point out that people will still want attractive, capable bodies for sex, aesthetics, safety, and pleasure of movement, regardless of economic necessity.
- Office culture and long hours are blamed for sedentary lifestyles; yet some note that even a minute a day of simple exercise can noticeably improve strength.
- A few worry more about “mental muscle” atrophy from AI tools than physical atrophy from automation.
