Well, Intel announced the first terahertz transistor over two decades ago, but there's still no terahertz processor. I wouldn't hold my breath for a petahertz one anytime soon.

That depends on what you mean by 'processor'. Optical systems are great at linear processing, but terrible at nonlinearity. You wouldn't want an optical processor based CPU to run Doom. Encoding something like an AI model or a codec into an optical processor would be great though.
