@XFreeze Elon's doctor can't wait to get to the moon and drive his @Tesla there. (Real image, not AI).

Going to the Moon first solves the most fundamental problem: iteration speed Building a civilization on Mars requires solving humanity’s toughest engineering challenges, but Mars’ brutal timelines make rapid iteration nearly impossible, every mistake costs 26 months and billions The Moon changes everything. It’s the perfect testbed to solve the four critical problems: • Sustainable off-Earth cities (life support, habitats, resource extraction) • AI-powered infrastructure (autonomous construction, robotics, decision systems) • Terawatt-scale space compute (fastest path to running AI infrastructure in space with unlimited solar power) • Cost optimization to fund the Mars mission Launch windows: Moon: every 10 days, 2-day trip Mars: every 26 months, 6-month trip

@elonmusk @tetsuoai Elon's doctor can't wait to get to the moon and drive his @Tesla there.

@tetsuoai To be clear, we are still going to do Mars. I don’t think this change affects the time to a Mars city being self-growing by more than 5 years and it might turn out to accelerate Mars.

SpaceX just shifted focus from Mars to building a self-growing city on the Moon, in under 10 years. Why the pivot? > Moon launches every 10 days vs. 26 months for Mars > 2-day transit vs. 6 months > 80x faster iteration loop > Uncrewed Starship lunar landing targeted for March 2027 "The overriding priority is securing the future of civilization and the Moon is faster." - Elon Musk The race to build humanity's first off-world city just got real.

"you point it at website and it just... tries to break in... fully autonomous with no human needed" "it stole the entire user database, all by itself, in 90 minutes"

@niccruzpatane @elonmusk Or, buy the 90% ready Intel Fabs… Money can buy happiness.

Elon Musk on building a Tesla Terafab: “Well, we make a little fab, and see what happens. Make our mistakes at a small scale, then make a big one.” This is the way.

@elonmusk Kind of like this?

Grokipedia is the future

And, according to @Grok, "Somalia does not strictly require documentary proof of citizenship (such as a national ID, passport, or birth certificate) for voting in its current and emerging electoral processes."

Very long list. America should require ID to vote. It’s a no-brainer!

While Sinclair's post references an old study from 2004, an @Grok analysis of newer, similar data corroborates the findings (see below). As a physician, I have noticed that lower body muscle mass (legs, thighs, hips) is associated with falls, injuries, morbidity much more than upper body (shoulders, arms, forearms). I see numerous older patients using canes and walkers, but don't see any patients with upper body assisting hardware. The seemingly logical and common sense conclusion is that exercise of the lower body musculature such as walking, running, cycling extends life by increasing muscle mass of the lower extremities, delaying the need for canes and walkers, and reducing the risk of falls and injuries which is a major cause of mortality in the older age group. Aerobic exercise of lower extremity musculature also simultaneously improves the VO2Max (oxygen utilization) which has been associated with a significantly reduced all cause mortality. Here's the Grok analysis of newer data>>>>> GROK: Yes, while the original study from 2014 analyzed NHANES data and found that higher muscle mass in adults over 55 was linked to a 19-20% lower all-cause mortality risk, multiple newer studies and meta-analyses (post-2014) have largely corroborated this association between low muscle mass and increased mortality in older adults, with some nuances around factors like BMI, ethnicity, and measurement methods. No major studies outright disputing the core finding appeared in my searches, though some highlight variations in strength of association or call for more research on specific subgroups. Here's a breakdown of key recent evidence:A 2023 systematic review and meta-analysis of 16 prospective cohort studies (over 81,000 participants) found that low skeletal muscle mass index (SMI) was associated with a 57% higher risk of all-cause mortality (pooled relative risk of 1.57). This held across age groups, including those 65 and older (relative risk of 1.56), and was even stronger in individuals with higher BMI. The analysis noted high heterogeneity, partly due to differences in BMI, geography, and measurement tools (e.g., DXA vs. BIA), but sensitivity tests confirmed robustness. A 2021 systematic review and meta-analysis of 9 high-quality studies (over 10,000 community-dwelling adults aged 65+) showed that deceased individuals had significantly lower appendicular skeletal muscle mass index (ASMI) compared to survivors (standardized mean difference of -0.18). The association was independent of muscle strength to some degree but modified by BMI and ethnicity. This reinforces the prognostic value of muscle mass assessment, aligning with the 2014 findings. Other recent cohort studies echo this: For instance, a 2023 study using UK Biobank data (nearly 500,000 participants) linked low SMI to higher all-cause mortality, with risks elevated further in certain subgroups like those with cardiometabolic issues. A 2024 meta-analysis on lean mass in middle-aged and older adults reported a 30% higher mortality risk with low lean mass. Additionally, a very recent (2024) study found associations between muscle wasting and a 51-75% increased mortality risk, depending on the indicator used (e.g., lean mass or grip strength). These build on the original by incorporating larger datasets, longer follow-ups, and adjustments for confounders like metabolic syndrome or physical activity. Some emphasize that muscle strength or quality may play a complementary role, but low mass remains a consistent risk factor. If you're interested in specifics like sarcopenia definitions or interventions (e.g., resistance training), I can dive deeper.
