<p>"Our most likely estimate is that replacement costs are approximately $91 billion. Military and strategic assets — nuclear facilities, missile and drone production infrastructure, air bases, naval vessels, and air defense systems — make up roughly half that total, at approximately $46 billion, which is equivalent to 4-6 years of Iran’s pre-war defense budget"<p>How exactly did they arrive at this estimate?  I would like to see a building-by-building breakdown, or at least a methodology.  Feels very vibe-researched tbh.</p>

<p>> 8 queries implies 8 tables, which is well under the limit for both Postgres and MySQL where the planner may give up and choose a suboptimal plan.<p>I'm not sure thats true for Postgres.  optimal join ordering is np-hard, and finding an optimal join requires exhaustive search through n! combinations (n=number of joins) - thats why postgres generally uses heuristics to figure out join order. 8 is also the default value of "join_collapse_limit" setting in postgres, so it can't ever reliably optimize over 8 joins at a time. Additionally, postgres starts using "genetic algorithms" aka testing random combinations of joins with 12 joins by default (geqo_threshold setting).<p>I generally agree its better to use database to its fullest, but I would say 8 joins is probably the "limit". Internally at work I've advised teams to try to avoid anything more than 6 joins for "hot-path" queries.</p>

<p>Not an Elon fan, but markets dictate the value, not analyst reports or "fundamentals".  The stock is simply worth whatever people will pay for it.  The fact that people are paying an implied valuation of 2T for it currently is a strong signal IMO.</p>

<p>excellent article.<p>> The key correctness insight is this: any two majorities of nodes must overlap in at least one node. So between any two consecutive global state changes — whether two commits, two leader elections, or one of each — at least one node participated in both.<p>intuitively makes sense, but would be nice to see this result explicitly derived or illustrated the same way the fano planes were.</p>

<p>yes, there is counterparty risk with both etfs and mutual funds.  in general, stick to the well regarded issuers or fund managers.  vanguard is the best imo, they do a lot to protect their shareholders.</p>

<p>The number of ETFs isn't as relevant as the total % of funds invested in passive funds as opposed to single stocks or active funds.<p><a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=5259427" rel="nofollow">https://papers.ssrn.com/sol3/papers.cfm?abstract_id=5259427</a><p>> Passive capitalization-weighted index funds now surpass active management in aggregate investor allocations. Flows into passive strategies cause unrelated stocks to move synchronously, undermining diversification and potentially increasing systemic risk. New flows into passive products mechanically overweight overvalued stocks and underweight undervalued stocks due to market-price weighting, exacerbating momentum-driven price distortions. Rebalancing at the stock level to non-price-based anchor weights may mitigate these distortions and enhance long-term returns.<p>This is likely why large-cap stocks have outperformed over past decade.</p>
