<p>They can take the other side of your other themselves, lose money sometimes, but make it up in the premium they charged you in the first place (or in the old days, from your other trading fees or your monthly subscription payment).<p>Cloud providers would be taking way less risk interacting with their own services than a broker does interacting with the market. Perhaps they would be more at risk from bad actors, but it shouldn't be significant: they could reserve this behaviour for people who have already spent, say, $100 with them so you can't abuse it at scale.</p>

<p>It's an important distinction because it prevents the defence of "oh it's just an old law, there are lots of old laws on the books that everyone knows aren't relevant, they can't be tidied up for political reasons".<p>It was suspended for the last 15 years! Surely it was easier to leave it suspended and unsuspending it is a conscious choice.</p>

<p>QQQ is the same as Nasdaq, for this meaning of Nasdaq.<p>The article isn't a great source, agreed. But it does give this calculation:<p>> Oddly enough, had SpaceX entered the Nasdaq-100 with a market capitalization of $1.75 trillion on Friday, March 27 [assuming the new rules (?)], it would have supplanted Tesla as the fifth-largest holding in the benchmark. The electric vehicle stock accounts for 3.8% of the Invesco ETFs.<p>So it would come in somewhere above 3.8%, by those calculations. And it depends on market prices from day to day. Not much changes about the argument above if you make it 3% or 6%, holding constant the assumption that it's 30% overvalued.</p>

<p>Actively managed funds like that charge around 0.5% to 1% a year. E.g. [0] The most prominent Nasdaq ETF, QQQ, charges 0.2% [1]<p>Spacex will be around 4.5% of the index [2].<p>If you believe the thesis of the article that Spacex is about 30% overvalued, and if the only advantage your fund manager has over the rest of the market is that they will avoid Spacex, they will save you 1% of your money over the lifetime of your investment. Assuming you're saving for retirement in 30 years time, the fees will cost you 15% or more.<p>Maybe your fund manager finds a Spacex-level mispricing every two years. In that case, they're worth the fees. Some people will tell you nobody can beat the market. My employer among others believes very strongly in the idea that some people do make better investment decisions than average. What is certainly true is that not everyone does.<p>[0] <a href="https://helpcenter.ark-funds.com/what-is-the-fee-structure-expense-ratio-of-ark-etfs" rel="nofollow">https://helpcenter.ark-funds.com/what-is-the-fee-structure-e...</a><p>[1] <a href="https://www.invesco.com/qqq-etf/en/home.html" rel="nofollow">https://www.invesco.com/qqq-etf/en/home.html</a><p>[2] <a href="https://www.fool.com/investing/2026/04/01/how-the-spacex-could-affect-these-popular-nasdaq/" rel="nofollow">https://www.fool.com/investing/2026/04/01/how-the-spacex-cou...</a></p>

<p>It doesn't take extreme memory on your part to remember to avoid that opening after the first 9 losses, or indeed the first one.

<p>Meh, I think the description is accurate. AlphaZero did pioneer neural networks for board evaluation, even if there was prior art on this. AlphaZero also showed a revolutionary new approach to search and training which Stockfish did not adopt, but that doesn't make the first part wrong.</p>

<p>Doesn't it also make sense in the context of modern networking assumptions?<p>I've never had to connect to PostGres in an adversarial environment. I've been at work or at home and I connected to PostGres instances owned by me or my employer. If I tried to connect to my work instance from a coffee shop, the first thing I'd do would be to log in to a VPN. That's your multiplexed protocol layer right there: the security happens at the network layer and your cancel happens at the application layer.<p>This is a different situation from <i>websites</i>. I connect to websites owned by third parties all the time, and I want my communication there to be encrypted at the application layer.</p>

<p>I don't understand your point. Are you saying that it's possible to get adequate training on a real ship, and using the fact that you managed to do it as an example?<p>Of course it's possible to train on a real ship. But the sailors who trained on models have <i>certain specific experience</i> that you will hope never to get. As for the things you experienced and they didn't, they can catch up with those during their first year on a real ship.</p>
