The universe is not a black hole because the "Schwarzschild radius equation" only applies in a very specific/narrow circumstance, namely a perfectly spherical, non-rotating mass surrounded by vacuum in flat spacetime.

Applying that equation to the observable mass of the universe violates basically every single requirement needed to apply the equation.

>light is assumed to not interact with gravity in that framework in any way.

Light absolutely interacts with gravity in Newtonian mechanics. One of the neat features of Newtonian gravity is that gravitational charge (which is mass) equals inertia so the two cancel each other out exactly in the equation of motion. No other force has this property.

This means gravitational acceleration is independent of inertia, even in the case where inertia/mass approaches zero.

One significant difference in interpretation that layfolks do consider important is that it's possible to exit from within the event horizon of a black hole in Newtonian gravity (without exceeding the speed of light) whereas in general relativity that is not possible.

In relativity the event horizon really is a point of no return, whereas in Newtonian physics it's the point at which escape velocity is equal to the speed of light. The escape velocity on the surface of the Earth is 11 km/s, but that doesn't mean that I as a human can't escape the surface of the Earth momentarily just by jumping and I certainly don't jump 11 km/s or even 1 km/s for that matter.

Similarly in Newtonian gravity it would be possible for an object to enter the event horizon of a black hole, and then "jump" back out at a much lower speed than the speed of light and then get sucked back beyond the event horizon, and you can in principle do this over and over again so long as you had some sufficiently powerful source of thrust.

In general relativity this is in principle not possible.

Having a terrible experience seems like a local issue, certainly some areas might have a worse pool of delivery personnel than others but where I live the people doing Instacart are primarily women and they do an excellent job. Many women can't do Uber because of the insane levels of harassment, but they are able to do "gig" work like Instacart or UberEats that doesn't involve interacting with random strangers.

Like most things in life, it's not a matter of difficulty, as if I am so incapable of going to a grocery store to buy groceries and the undue hardship it will cause me. It's simply a matter of how I like to budget my time. I judge that the 30 minutes it can take to do groceries is better spent doing other things with my life.

Not at all. The asymmetry holds whenever the other possibilities don't introduce an opposing infinite penalty for belief. There could be countless other gods who are indifferent to Christian belief, reward it, or impose only finite penalties, and the asymmetry would remain intact.

The hypothetical god who punishes believers of a Christian God is a legitimate objection to Pascal's wager, but it doesn't establish the original assertion I objected to. You're confusing demonstrating that the asymmetry isn't guaranteed with demonstrating that it requires Christianity to be the only possibility. Those are two entirely different claims.

Pascal's wager was not at all anchored to any specific attestations, you are taking his wager and reinterpreting it to give it some kind of legitimacy that it never originally held. The entire point of the wager was to justify belief in the absence of sufficient evidence, by appealing to the asymmetry between infinite reward and finite cost. If your now arguing that Christianity is more credible because of historical evidence, so be it and stick to it but you've abandoned Pascal's wager and moved on to an entirely different argument.

If this claim was in writing then it's legally binding in most U.S. states. Technically it's legally binding even if it's not written but in those cases it's harder to prove.

Yeah, you're referring to Scott Meyers and he gave a really insightful talk about how complex and inconsistent C++ has become here titled "The Last Thing D Needs":

https://www.youtube.com/watch?v=KAWA1DuvCnQ

Slides are here:

https://www.aristeia.com/TalkNotes/TheLastThingDNeeds2-ups.p...

The conclusion is "The last thing D needs is someone like me." meaning D should avoid designing a language where you basically need a niche of lawyers crawling through the language standard to decipher the meaning of various features and then write about how to safely use those features. It's not that languages shouldn't have experts who give good advice, but that the nature of advice in C++ has come down to explaining arbitrary rules, inconsistencies, and obscure corner cases rather than how to use the language effectively to solve actual problems.

He says at some points (taken from the transcript):

"There are some arbitrary, wacky decisions, in my opinion ... There's a lot of, in my opinion, simple arbitrary choices that did not have to be made that make explaining things more complicated and also make working with the tool more complicated."

"Much too much of what I've written about has been tool use, talking about language idiosyncrasies, arbitrary decisions, things you need to be able to remember."

"There is epicycle on epicycle on epicycle inside this language."

And then he followed it up a few years later with a blog post explaining that he won't be updating his book with language related fixes because he no longer trusts himself to know what's right from what's wrong:

"C++ is a large, intricate language with features that interact in complex and subtle ways, and I no longer trust myself to keep all the relevant facts in mind."

It's a misleading number, the 500 billion in revenue is needed over a 10 year period, it's not a yearly figure. Anthropic isn't paying 500 billion a year for the commitments that OP posted, it's paying 500 billion between now and 2036.

The OP post is misleading because it makes you think Anthropic has to earn 500bn per year in revenue, but those commitments listed are not yearly commitments, they're commitments over 10 years with contracts that run until 2036.

Anthropic needs to earn 52B a year in annual revenue to honor those specific commitments plus obviously its own operating expenses... and yeah that will require Anthropic to grow as a company, but their S-1 indicates 67.2B a year in revenue and sure maybe they stop growing and this is their peak... or maybe they do manage to grow further to 80B a year, 90B a year...

These commitments aren't annual though, most of them amount to 10 billion a year commitments for 10 years. Put another way Anthropic has committed 52 billion dollar a year to these companies and their S-1 indicates they earn 67.2B a year in revenue.

I'm not going to predict whether Anthropic succeeds or fails, just that it's very misleading to claim that Anthropic needs to grow to $500b in revenue without making it clear that it's $500B in revenue per decade rather than $500B in revenue per year which is what most people reading such a number would assume.
