People are rightfully pointing out how ridiculous some of the overt substantive changes in that end poem are, but I was pretty amazed by how even the quite minor changes totally alter the feel of the thing too.

"Sit on a couch and look at a wall"

to

"Laying on the couch and looking at the wall"

loses a lot somehow in a hard-to-pin-down way. It's almost an impressively efficient butchering

Especially if enough Amazon internal tools rely on it - would be funny if there were a repeat of the FB debacle where Amazon employees somehow couldn't communicate/get back into their offices because of the problem they were trying to fix

Is there a correlation between wealth and loneliness? I could definitely imagine it being effect for the poorest in society but I wouldn't be surprised if, once you've reached a threshold of being able to keep your head above water, money and loneliness had very little relationship if at all

Unless I'm mistaken (very possible), the existing cubic Newton method they discuss already has this convergence guarantee, but introduces a lot of extra expensive work at each step. The specific contribution of the paper is finding clever regularization tricks to keep this guarantee while sidestepping the extra hassle the cubic method needs

How much of that is revenue from actual crypto-related business vs. just appreciation of crypto the company owns? Feels like the impressiveness of this trend really depends on that

You can be honest and accurate without being needlessly nasty/mocking as the quote seems to be

Your sentiment is a really common and insidious one that way too many people use to feel smug and "rational" about being mean

The analogy to companies doesn't work because there isn't a legal mechanism by which you can make your short predictions come true. It's illegal to manipulate markets and most ways by which you could destroy a company (without spending more than you hope to gain) are also probably illegal. If you can think of any legal ones I'd be curious to hear

If it were legal to take a short position in a company and then take actions which blew the company up AND there existed cost-effective ways to do so, then you would definitely have seen more legitimate companies taken down by short-attacks. In contrast, here you have an entity where (a) there isn't the same legal safeguards and (b) there exists a claimed cost-effective way to tank the entity after taking a short position

If you disagree with (a) or (b) empirically then cool but it's clearly a totally different scenario to regular companies

Probably a heretical thing to say here but I feel like PG has increasingly fallen into the trap where because he's been smart and insightful in some areas he's gradually convinced himself he's smart and insightful everywhere. IMO the more he veers away from writing on e.g. coding and startups the more he comes across like a very over-confident man who thinks he's figured it all out

It's quite noticeable on Twitter too where he seems to increasingly have very confident diagnoses on everything from geopolitics to culture war nonsense to genetic engineering.

Funnily enough a friend said something lately about SlateStarCodex (or ACX now) - I wonder if getting that much positive feedback on your musings just inevitably starts convincing you everything you think must be just as insightful

I think this is right - my experience as JS and similar places is that really understanding your data-generating process and the nitty-gritty assumptions of your data/simple model makes a huge difference

E.g knowing what's causing missing values in your data and what implications various fixes on that might have on bias in your linear regressor is probably way way more valuable than fitting some shiny non-linear toy

You're right overall that most of these places are a lot less flashy on the inside (have worked at a couple). Linear models everywhere as you said

However I think you're underestimating RenTech here. They're genuinely just in another league compared to what most people consider the "elite" quant shops. You're not getting in unless you're an actually impressive academic with a track-record, so I wouldn't be surprised if they're trying some weird stuff that other shops can't even understand (although I would imagine in small size vs. more vanilla stuff).

IMO places like JS/CitSec do a really good job of bombarding campuses to inculcate this idea they're the absolute apex of mathematical wizardry, but the places that are really doing some dark magic shit aren't trying to get undergrads to apply to them. Ofc maybe I'm falling for the same kind of propaganda for RenTech
