<p>I think what you wrote makes sense, and you missed one critical aspect : shared access to excessively expensive capitalized facilities and equipment.<p>One example from 1985 onwards that i can think of is NSF funding of supercomputer centers.  40 years ago, SIMD / vector processors with boatloads of memory were not ubiquitous, nor were shared memory multicore / multiprocessors, a situation which differs with the reality today.<p>This NSF funding established the 5 supercomputing centers<p><a href="https://en.wikipedia.org/wiki/National_Science_Foundation_Network#History" rel="nofollow">https://en.wikipedia.org/wiki/National_Science_Foundation_Ne...</a><p>and then further downstream effects include popular access to creations from the supercomputer centers, such as Mosaic from NCSA, and an expansion of ideas outside the compuserve / aol paradigms.<p>I think similar situations apply for other engineering disciplines, mechanical and chemical and physics and so on.  Probably true for the arts in various forms:  people don't have personal pipe organs to learn Bach on, for a crazy example, but universities do.<p>For various industries, learning requires physical equipment too expensive for individuals, historically and still.</p>

<p>agreed...thought of that after writing it, and thanks for noting it too.<p>i thought the order of magnitude is often hipster phrasing, even on HN at times, but, when actually intended, it's like saying floor(log_base10( whatever )), so the ten times thing would have to be "roughly ten times" for example, to be comparable.<p>Also, in some contexts the base isn't presumed to be 10, of course, though around here in loose jargon that's usually what folks are saying.</p>

<p>"order of magnitude" seems to also be silly-speak very often, trying to sound more technical than "ten times".<p>i suppose it is similar to "exponentially" being used when it doesn't mean exponentially.</p>

<p>this is misleading:  Apple sources external datasets for maps and continuously imports, which used Scala last i knew, so the question is what upstream map source is removing Lebanese sites?</p>

<p>Apple maps used (last i knew) Scala to import externally sourced map datasets continuously, and those may have lost towns and villages in Lebanon.</p>

<p>i'm pretty sure that in Arizona, and i think in California, they DMV sends the title updated to show the original holder (like BMW Financial Services, Subaru Financial Services, or whatever) has been payed completely, and the person is then shown as the title holder.</p>

<p>Ahhh, like if you were to put your new VW on your Visa card entirely.<p>That might work: you'd have bought the car, from the point of view of VW and your DMV, so the DMV sends you the title, not Visa.</p>

<p>> They just dump money into your bank account and say "please buy a car with this" and you keep the title.<p>where is this?<p>you don't have or keep the title until the bank sees you paid off the loan, in every instance i've seen.</p>

<p>that's a stretch: andreessen got wealthy because he worked for the UIUC group in a project which turned out super popular, super funded by Jim Clark, and got massive explosion in worth.   there's no sociopathy involved from him back then.<p>Musk made a company that jumpstarted some wealth and invested in other things which exploded.<p>Toto Wolff is a gazillionaire because he too made some pretty incredibly timed investments.<p>point is, extreme wealth results from some combination of work, timing luck, strategy, and sociopathy, but they're not all required to span the space of wealthy people.</p>
