> It seems to be reversing, at least among affluent kids.

America is not solely made up of affluent kids.


Is this a trick response? There's no way he ever cared about society in a way that wasn't completely plastic.


Sure, for some variation on the meaning of “society”, or “care”, or “plastic”, and maybe all the best ones, but it’s hard to argue he had never seen value in groups of people before starting Facebook, and arguably a motivator for every human being ever born.


How do you sleep at night?


I have never read a more (intentionally?) cryptic and needlessly philosophical praise of cryptocurrency in my life.

Deeply uninformed person here:

Is the inference cost of generating this tree to be pruned something of a hindrance? In particular I'm watching your MNIST example and thinking - does each cell in that video require a full inference? Or is this done in parallel at least? In any case, you're basically memory for "faster" runtime (for more correct outputs), no?


This understanding is incorrect. The video samples all the leaf nodes of the entire tree only to visualize the distribution in latent space. In normal use, only the L outputs along a single path are generated.


Interesting, thanks for clarifying.

You can't ban people from roles because they sound like a more famous person.


Yeah I'm curious about this myself. Seems to utterly destroy CPython in every one of those benchmarks.


*for very specific benchmarks, not "on average"


True, Python could be better or worse than two orders of magnitude slower for your particular use case, but it's 70x slower for recursion and addition that it clearly hasn't special-cased. That's good to know.



For compute-heavy code "100x slower than C++" is a good rule of thumb in my experience in python 3.10.


Maybe when you are reinventing the wheel instead of using e.g. numpy, Jax, PyTorch. Python is an ecosystem some of which is tooling built in C/C++. There’s no reason to ignore those libraries just because C devs like to roll their own everything.


There's an Amdahl-like effect, where "100x slower" means that anything nontrivial in pure python ends up being fat in your flamegraphs, even if your "heavy lifting" core algorithmic stuff uses some nice fast libraries.

quick n dirty Python code will run faster than quick n dirty C++ code


He may be right, everything points to that conclusion. My main issue is - why the fuck do we care what Bezos thinks on this matter? His ML efforts all lag behind the competition and he’s certainly not an expert in the field of deep learning. Why?


Why would you name a gaming adjacent system “PortalVR”? I doubt you’ll get in trouble for it but you’re going to confuse so many Portal fans (and there are a lot of them).


It's a pretty common word and the last real portal game was 14 years ago. I don't think it's that confusing.

And there's already a VR headset named Portal that's not confusing those fans.

Though uh that one has some potential for confusion.


Three years ago in a very real sense https://en.m.wikipedia.org/wiki/Aperture_Desk_Job


I put "real" in my sentence explicitly to exclude these little control demos. Half an hour long, no portals, whatever sense it's a "very real" portal game is getting outvoted by the other senses.


Nope the last was released 9 years ago and it was ironically a VR-only game: https://store.steampowered.com/app/446750/Portal_Stories_VR/


That is at least officially a mod for portal 2, and also it's not by Valve. It doesn't count as a real portal game.


I was going to name it Portal, but I named it PortalVR to minimize confusion.

It’s called PortalVR because there is no better name to describe what it’s like to play VR this way. It is like playing games by looking through a portal you hold in your hand.


Yeah please don't change this based on the thoughts of just one Portal fan. If you like the name, keep it.


Portal is pretty old at this point. And realistically you can only expect to get dibs on a generic word for so long.


Sure it's just bizarre for me as a dedicated Portal fan. I just replayed Portal 2 a year ago so it's still fresh for me.

If they're truly attached to it they shouldn't change now of course.
