(I swear I’m not in Fridman’s payroll.)

As a layperson I found this episode with Jeffrey Shainline an interesting discussion tangential to the topic of optoelectronic computing. The basic gist was that photons are good for communication, electrons are good for compute.

The specific timestamp for that part of the conversation: https://youtu.be/EwueqdgIvq4?t=2793
Not in the domain but as far as I understand from video for the counter argument: "Adding a matter of component and creating this kind of liquid of the light you add interactions in the system so practically light interacts more efficient with the light"

This makes me wonder if transmitting data optically would help with the gradual lowering of the data/compute ratio over time:

We already transmit data optically, that's what fiber optics is.
I'm talking about between chips and RAM of course because that's where the data/compute ratio is shrinking, not between Tokyo and New York.
the hard part is that currently electrical to optical conversions take a fair amount of space which would make them hard to do on CPU. it might be practical for storage to ram though, which would be really cool.
