I just went through the DSGE wiki page [1]. It says the following about the model, which if true, then I can see why it is an completely unserious model.
> Below is an example of the set of assumptions a DSGE is built upon:
> Perfect competition in all markets
> All prices adjust instantaneously
> Rational expectations
> No asymmetric information
> The competitive equilibrium is Pareto optimal
> Firms are identical and price takers
> Infinitely lived identical price-taking households
> Distortionary taxes (Labour taxes) – to account for not lump-sum taxation
> Habit persistence (the period utility function depends on a quasi-difference of consumption)
> Adjustment costs on investments – to make investments less volatile
> Labour adjustment costs – to account for costs firms face when changing the level of employment
Are these not the 'friction can be ignored' assumptions of economics? They are, of course, blatantly false. But that doesn't stop such models from effectively modelling real-world behavior.
Granted, I know a slight bit about general equilibrium theory, but nothing about DSGE.

I'm always surprised when people suggest using a different language if you want typing in Python. Python's (second?) largest appeal is probably its extensive ecosystem. Whenever people suggest just changing languages, I wonder if they work in isolation, without the need for certain packages or co-worker proficiency in that language.

I know I am going to be in the minority, but I don't understand why we can't let Python be Python. Static typing is great, and there are already other statically typed languages for all your needs. Why not use them?
Well, at least it doesn't create two incompatible Pythons like async and (I assume) free threading.
> Why not use them?
Because you can now use typing WITH the entire Python ecosystem.
HN is usually negative, cynical, skeptical, eyerolling, regardless of topic.
Just the other day someone posted the ImageNet 2012 thread (https://news.ycombinator.com/item?id=4611830), which was basically the threshold moment that kickstarted deep learning for computer vision. Commenters claimed it doesn't prove anything, it's sensational, it's just one challenge with a few teams, etc. Then there is the famous comment when Dropbox was created that it could be replaced by a few shell scripts and an ftp server.
Thanks for linking that thread. Really puts things in perspective.

I disagree with this and what Dinnerbone says about locks. It doesn’t matter who file was intended for, it’s on the internet, if people want to use their silicon to do some mathematics to turn some numbers into some other numbers that’s their choice. It’s not equivalent to breaking into a house.
I personally don't see downloadability as a significant factor in the morality of breaching security. If it's bad to hack a login screen to gain access to private information, why wouldn't it be bad to hack encryption to do the same thing? What moral dimension does downloadability alter?
I think the house analogy fails because you cannot duplicate a house, take it somewhere else, and attempt to break into it there. If you could, that would undoubtedly be seen as a violation.

My then-gf (now wife) and I watched a movie together about an African man whose village got raided, him put into slavery to search for diamonds and his son becoming a child soldier by the same people and their struggles to get free, and finally pawn off a pink diamond to one of the largest diamond companies in London. At the end of it, she finally came to realise that the diamond trade was really quite shitty. And we had a long discussion about the whole thing, as well as the growth of the synthetic diamonds industry and how they’re much better on the supposed 4C properties as well as on price.
Yet in the end she still wanted to get a ring from one of the big names because that’s what she grew up with and what she had always dreamt of since young.
¯\_(ツ)_/¯
Similar story here. Goes to show how effective brainwashing kids as an advertisement technique is.

No credentials whatsoever - IIRC a Bachelor's degree in English, but definitely not a professorship.
