Stephen Hawking's impact on computer science In light of Stephen Hawking passing away today, I was wondering whether any of his results have direct impact on cs? 

The obvious candidate would be in quantum computing, or rather the construction of a physical quantum computer, but perhaps there are results that have other impact.

I am familiar with his work only on the popular-science level, so this is not really a research-level question, but perhaps it has research-level answers.

EDIT: following the answer, I don't mean his recent concerns about AI. That is not really a contribution to CS, more of a philosophical/sociological point. I aim more for mathematical results, or connections of physics to computing.
He didn't have any major impact on computer science.

His writing in computer science are limited to popsci and more recently raising public concerns about AI.
