"a time when immersive digital worlds become the primary way that we live our lives and spend our time". even as someone who frequently posts and reads web content, that sounds hellish.

programs are, fundamentally, tools for control. if we're meditating our interactions with the real world primarily through digital systems, it begs the question of who holds the reigns of that system. with the real world, you have the saving grace that no one can fully architect what can and can't be done, but in a constructed space, there is substantially less freedom.

That's not to say that the systems we have can definitely be fully architected: there are limits to what we can express in code, and formal verification is really hard. (Let's not even start on things like covert channels.) Still, even Mastodon, Twitter, Facebook, etc, shape the kinds of interactions we can have: we have character limits, limits on the number of images per post, but also the clients privilege some actions over others by putting their buttons in more prominent, easily accessible places.
