Question 100 GHz light-powered chip

In today's news:

China’s 100 GHz light-powered chip ditches electricity, shatters speed record in computing

Without knowing details such as the number/type of gate/transistor equivalents there are, the cost of manufacture, the power requirements and so forth it isn't that relevant to "CPUs and overclocking".

It isn't useless if it just used like the example for a frequency comb, or filtering or the like. But let's find out if it can even implement a 6502 before we make shocked face reactions. It probably will have very different roles - most likely roles that involve incoming and outgoing fiber optic connections where the speed is less important than avoiding wasteful transitions to/from electrons.

I'm going off the article, which is clearly written by someone without a lot of technical knowledge on the matter, but it seems like their design is more to replace traditional PLLs than any kind of compute chip.

Confirmed it can not play minecraft... so its a fail... (sarcasm)

I wonder if the future of hybrid computing might be something like this handling ST duties while traditional silicon solutions handle MT compute? As we know there is nothing like frequency when it comes to ST performance. One hyperfast light-powered core running at 50GHz and 64 traditional silicon cores sound nice!
