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)

So they have some kind of nonlinear material that can make light modulate other light, that they managed to get working at teraherz frequencies?
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)

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.

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.
