No, HN is a small community of people who share a narrow set of interests. Although that set of interests is broadening and I think HN is worse for it. While the community does include people from all over the globe and thus is in a literal sense global. It's not global in the sense of attempting to include and cater to everyone. If there are people who don't see much value or enjoy HN much the HN staff doesn't seem to have much interest in changing their minds.
Hacker News really doesn't have the scale to be considered a global community in the sense that's being described, and it harbors a culture which self-selects against general purpose content in order to prevent itself from becoming that global community.
The "global" version of Hacker News would just be a text only Reddit.
