I don’t know anything about this field. Can you address this point? How close are we to overcoming this in academia?

At milliwatt power, and terahertz frequency?
PowerElectronix [3 hidden]5 mins ago
I guess it's a theoretical limit as in the material can change properties that fast given a fast light signal.
amelius [3 hidden]5 mins ago
I mean, researchers have been trying for years, what is different now?
octoberfranklin [3 hidden]5 mins ago
Yes; this material is called "snake oil".

Let's see if the investors bite.

Theranos demonstrated that they'll bite at anything.

I didn’t read but I’d also like to point out photonics are 1000x larger than leading edge electronics with minimal path to scaling smaller. I don’t see a free lunch
userbinator [3 hidden]5 mins ago
Basically the density of early CPUs (1970s), but 1000x faster than those, or current CPUs? Like a 1GHz 6502, or a 1THz 6502? The former is not really better, but the latter might interesting.

There ain't no free lunch, but real progress rarely depend on it. It's usually lunch we weren't eating before, or a different way to eat the same lunch but with much more satisfaction.
jurschreuder [3 hidden]5 mins ago
It's just as if he had the brilliant idea to do photonics as an outcast even though there is already a 6" wafer semi-production level fablab being built for it in The Netherlands. There is even a version of TinyTapeout for Photonics.

What's this photonic Tiny Tapeout?

Finally! This paves the way towards practical BrainF*** execution.

This comes up every couple of years, but it hasn't seem to have made any advances since the first time I've seen this.

The channel's other uploads may be giving us a glimpse into this project's future.

Yup. UFO conspiracies, aliens on the moon, PSI...

Interesting topic, unreadable due to sloppification.

"The first thing to understand about Akhetonics’ optical computer is that it’s not one thing yet." Great, that is such a good explanation. Thanks ChatGPT I guess.

Now it's a good case to use your own ai to un-sloppify

> Photonics
So also 1000x smaller integration
amelius [3 hidden]5 mins ago
Why?
dvh [3 hidden]5 mins ago
Light is hundreds of nanometers, smallest "transistor" cannot be much smaller than wavelength.
Y_Y [3 hidden]5 mins ago
In honour of Akhenaten? Cool.
nekusar [3 hidden]5 mins ago
References of Akhenaten is making rounds in modern pagan/occult circles as well. The "Law of One" group is really pushing ancient Egyptian 'pyramid power' stuff.
natas [3 hidden]5 mins ago
This has been tried by Cray like 15 years ago and the university of Colorado 11 years ago; there were also other initiatives, all failed.
I'm not excluding that now we have more budget/time/AI to make it work (if it can), I'd just say exercise caution reading this (very AI slop) article (and anything that looks too good to be true)
mbfg [3 hidden]5 mins ago
interesting that it is still 2 bit
kmoser [3 hidden]5 mins ago
Do you mean as opposed to operating in an analog fashion? My guess is because keeping it digital means it is as close a possible to a drop-in replacement for today's electronic digital computers, including all the firmware, OS, and software that has already been written for them.

Sounds incredible, as in: can't believe it.
By the way, isn't Nvidia researching this?
Very real stuff (I have a PhD on this)
