If recursion is confusing to people then files are a great weeding out function for folks studying computer science. We have too many clueless people in the industry, why add more?

Bundles are just folders with a bunch of files in them. How does that invalidate the concept of files?

We're talking about why smartphones and tablets are designed without emphasizing files, and why students start CS courses without knowing what filesystems are. That's the reason. By all means, weed out everyone who isn't already self taught in desktop computing skills, that's a different discussion.

Bundles are an attempt to simplify file format development, or can be seen that way, but it failed exactly because they are folders not files, and therefore aren't really usable because they can't be easily transmitted. You can't drag a bundle onto an email, or upload it to a file sharing platform, or send it via Bluetooth. Apple used to use bundles for iLife word processor documents, spreadsheets etc. They had to give up because it caused too many problems. Nowadays they use ZIPs like everyone else.
