Why does Discourse need 1 GB of RAM?

While I understand the whole “preparing for the next decade of the Internet” thing, 1 GB of RAM minimum is still a pretty aggressive and expensive requirement, especially for smaller forums. It may be $10 a month on DO but that’s twice what I pay now for a 512MB setup with 3 php-based forums on it that are barely breaking even with hosting and domain costs.

You could argue that the requirement keeps a lot of crappy forums being prevalent like it is with most free forum software though.
