That you can't backpropagate is a common misconception. There is recent work (I am one of the co-authors), that derives a precise analog of the backpropagation algorithm in spiking neural networks ( https://arxiv.org/abs

Not in any physically interesting way. This wouldn't have any chance of discovering the Yang Mills equations for example.

The word train is highly misleading here. Training a humans and “training” in Machine leaning refer to fundamentally different processes.

pocket watches existed at some point, glancing down on your wrist is way less annoying than having something attached to your shirt pocket all day.

Have looked at the T1 Code? It far from obvious how you would use that as a starting point for a new chip. You need a lot of expertise for custom memory blocks etc. and there aren’t any tests included if I remember correctly.

Julia is a language that was developed by academics, with not the best aesthetics in the implementation. I see a lot of value in starting with a clean, well engineered layered approach. If anything this is something I would expect Lattner t

They used to do nuclear physics research (and still do to some extend) there and had an experimental fast breeder reactor (capable of producing weapons grade plutonium) on campus. They also prepared for rapid development of nuclear weapons

The hardware they have in production is underpowered and wouldn't be able to render those high fidelity avatars. That is also why their version of the meta verse looks like it does. They want to be independent of the "legacy"

Ironically the very first publication on "Backpropagation" by a Finish master student (1972) already pointed out how to compute gradients in computational graphs. This if anything is the main thing which distinguishes Backpropagat

Being German and now getting first contact with bureaucracy in the US, I wouldn't be so sure that Germany is actually all that bad.

It is the same in many areas I think. You get in if you know someone, or have a prior established rapport. At the very least that is a way more pleasant way of finding a new job.

I've tested it on a various areas of expertise in physics that I am familiar with and it often makes up content which sounds very plausible except that it gets pretty much always details wrong in very important ways. On the other hand

Next level of the game is to invent the certifications in collaboration with regulators and then sell software that is certified.

GPT-4 is already at a level that it has graduate level math and physics knowledge, with a level of recall that most students can only dream of.

Well in both cases you can ignore a lot of unknown physical details and still reach a valid conclusion. In the case of the climate this is done in terms of energy balance for example. The details are super complicated but you also have hist

Measurements are adjoint to state preparation. Depending on what you measured you can prepare a special state at that time to make the system time reversal symmetric.

Volkswagen planned to hire 10000 new people for their "Car.Software" division in Wolfsburg, Ingolstadt, Berlin, as well as Seattle und Peking until 2025. They are also building up their hardware division with plans to do cutting

Have you lived in Germany? I would only consider going to the US for substantially higher pay. Also there are 80 million Germans, many of whom are fairly well educated and would like to work for Mercedes in Stuttgart.

Both Mercedes and Volkswagen have absolutely massive software divisions, easily 10k+ people. They pay really well for German standards and have access to a large talent pool of people that would like to live in Germany.

While in principle you can evaluate certain path integrals by using MCMC, in practice you run into all kinds of issues like the sign problem, which even with things like complex Langevin dynamics can't be resolved to this day completel

Even optical computing needs lots of standard electronics for storage etc. as you point out these consume most of the area, so we are talking about something that consumes 100x more area for a function which is not the main energy expensive

Visible light and near ultra-violet light has a wavelength ~400-800 nm, current gen transistors have a pitch of ~40 nm. This gets worse because scaling is actually either quadratic (2d) or cubic (future 3d integration). So we are talking ab

More power to them if it works, you can do cool things with it for sure. I am continuously amazed what you can do in quantum optics etc. but it isn't anywhere near to practical except for optical communication.

One of the things that I fully not expect to be successful is optical computing. There are just a lot of academic groups that are doing optics and they like to invent new reasons why whatever they are up to is relevant. For physics reasons

I am actually still unclear how AlephAlpha pulled that off and who funds them, since they have a rather low profile team.

It’s all hypothetical at this point, I reluctantly followed the guidance, more or less because I didn’t want to be inconvenienced too much. You are right I could have suffered worse, but then again I have absolutely no risk factors and stat

Ok, well then it might turn out that some of the fringe scientists were right all along. A healthy young male like me would probably have been far better off to not receive any kind of vaccine, I only got Covid after a third booster and I d
