Electro-optic conversion is expensive in terms of power, so you better be sure it's necessary. There are still some people looking at hybrid computers with both optics and electronics. To be practical, you'd need both to be realized in the same platform, but they don't exactly work on the same scales, and laser integration is a big issue.
