And perhaps security.  I wouldn&#x27;t be surprised if Google avoided standard C++&#x2F;JIT browser engines in favor of something custom entirely written in a safe language - but if they don&#x27;t, it wouldn&#x27;t be that hard to get code execution on (a sandboxed portion of) Googlebot.  Same goes for competitors - I don&#x27;t think the state of public safe-language browsers is that good, though I&#x27;m not sure.
