  • Except there’s evidence they do, in fact, go both directions.

    For example, DES had its s-boxes messed with by the NSA. At the time, the thought was that they were intentionally weakening it. Some years later, public cryptographers developed differential cryptanalysis for breaking ciphers. They found that the new s-boxes in DES made it resistant to differential cryptanalysis. It appears the NSA had already developed the technique and had made DES stronger, not weaker. Because again, they need to protect their own stuff, too, and they used and promoted DES to get there.

    They also gave it a really short key that was expected to be broken by the '90s, which is also exactly what happened.

    They appear to be going a similar direction with elliptic curves. They seem to be resistant against certain attacks, and the NSA was promoting them earlier than most public cryptographers.













  • If you invest in the sp500, you’ll have something around 8% return per year. This is highly variable year by year, of course, but in the long run, that’s what you can expect to average out. You can do better than the sp500, but generally not without accepting higher risk.

    With those returns, you will double your money every 9 years. Roughly. It’s going to vary by decade. 2000-2010 was flat, while 2010-2020 was unusually good.

    If you max out a 401k, HSA, and IRA on this strategy from a young age, you should have millions for retirement. If you’re a millennial or younger, you’re going to need a million or two (at least) to have a reasonable retirement.

    How do you turn that into a billion? Doubling every 9 years won’t do it in your lifetime. Not unless you started life as a millionaire and never withdrew a dime until you were 90. Starting with $1000 and doubling every year for 20 years, consistently, would do it.

    How do you double your money consistently for 20 years? Either extreme luck or doing something extremely shady. Probably both.

    In other words, they are not the genius captains of industry that right-libertarians want you to believe. They got lucky or are deeply unethical or both, and they do not deserve your respect. Most likely, they deserve your disdain. Every one of them.
