I was nodding along with the first paragraph. But then,
> The greatest threat to Emacs, [..] is a paradigm change in how software gets built or run
Is a little to far into scify land.
First it requires software to no longer be text based, and then it requires virtually all software to switch to this non-text based solution.
In that world a single user can keep Emacs up to date and compatible by asking our AI overlords to do it.
