I'm really not sure what the point of your post is but what I can tell is you've completely misunderstood my post (and possibly Kodi too?) because several of the conditions you highlighted (eg "todays", "non-technical") wasn't even in the scope of my monologue.

Besides, non-technical users wouldn't be ripping DVDs to a NFS / SMB share in the first place (or using a home server / NAS for bittorrent / usenet / etc if that's how one prefers to accumulate their video archive). So why would they want a Media Centre that's designed for playing local or networked content?

Maybe what you're referring to is the stuff that has been in press a lot in recent years; the stuff incorrectly named (imo) as "Kodi-boxes" (or similar). I say "incorrectly named" because they used 3rd party plugins for illegal streams but those really have naff all to do with the Kodi media centre itself. It's like calling illegal downloading "Windows-boxes" because someone uses a bittorrent client on Windows 10.

I guess you could argue that Kodi now fills a niche that is dying out - that's certainly the case for me as I tend to use Netflix et al on my smart TV. But for playing local / mountable files, Kodi still leads the pack in terms of ease. Which is hardly surprising when you consider that's what the media centre was built to do.
